THE COURSE
The 50 and 34 mile ultra runs are a wonderful amalgamation of a number of local running routes. The linear route climbs 1,143m and takes in the South Downs, the Sussex Ouse Valley Way and the Ashdown Forest, finishing on the idyllic Hever Castle estate.
This route was conceived in the dark days of the 2020 lockdown and first undertaken by five men and one dog (pictured) in August of the same year. It was to mark the 50th birthday of Race Director Brian Adcock (centre) and raised £10,000 for Macmillan Cancer Research.

YOUR RACE INFORMATION
The race route travels from the start at Eastbourne Pier along the promenade to the start of the South Downs Way (SDW) path. It then follows the SDW path to Birling Gap and then up and over the Seven Sisters to the Seven Sisters Visitor Centre. From here, still following the SDW the route tracks north to Alfriston and then heads west almost to the Firle Beacon before descending to the Ram Inn and the quintessential village of Firle. From here, the route heads north through Glynde and at Barcombe Mills joins the Sussex Ouse Valley Way. Once the rural idyll of Fletching is made, competitors are on the home stretch. A stiff challenge up and over the Ashdown Forest brings participants to the ancient parish of Chiddingstone and finally the back gate of Hever Castle with a well-earned trot around the grounds and the Finish Line as the prize. Read detailed route description here.
EASTBOURNE PIER - THE 50 MILER START
Runners will form up on the Eastbourne Promenade and the start line will be immediately in front of the entrance to the pier. On the klaxon runners head off down the promenade in a westerly direction for 2km. At the Italian Gardens take the path uphill to the right and then pass Bede Prep School on your left hand side before heading off-road and steeply uphill onto the South Downs Way (SDW) proper. A 3K climb uphill takes the runners to Beachy Head and a stunning view of the Channel, Eastbourne and The Seven Sisters. At 7.5K you will pass the Belle Tout Lighthouse (now a B&B) and then descend downhill to Birling Gap at 9K. A 4K stretch on the stunning Seven Sisters will see you descend to Cuckmere Haven and then make the 1st Feed Station at the Seven Sisters Country Park Visitors Centre at just over 14K.
FROM FRISTON TO FIRLE
Pass through the Friston car park heading to the NW corner to pick up the public footpath. After 100 yards take the left hand fork of paths and this will descend down onto the Litlington Road. Follow this lane with Friston Forest on your right hand side for just under 3K before turning left onto a public footpath just after the village signpost for Litlington. Cross over the River Cuckmere and then head uphill to the group of houses
9
that are roadside on White Way. Turn right and follow this road into the village of Alfriston for 2K. Once on the High Street take the first left on Weavers Lane heading uphill and then taking the 2nd left onto Kings Ride. This tarmac road becomes track at the edge of the village and continues straight on. Head uphill for 3K on the SDW path and then another 2.5K on the top of the downs before descending at a right hand fork downhill to the village of Firle and the second feed station at the Ram Inn at 26.5K. This is where the 34 Miler competitors will join the race.
VIA GLYNDEBOURNE OPERA HOUSE - THE 34 MILER START
Runners for the 34 miler will form at the Ram Inn feed station. The start line is immediately after the feed station. On the klaxon, the runners will head north, joining the 50 milers. Head North out of the village for 500m until you hit the A27 and then turn left on the footpath adjacent to the road until you get to the traffic island that provides the safest place to cross. Having crossed over the main road, turn left and continue on the pedestrian footpath for a further 300m before taking the first right turn that is a minor road. This will take you into the village of Glynde at 29K. Follow the road (Lacy’s Hill) through the village and onwards to the north for 3K passing the Glyndebourne Opera House on your right in the process. At the high point of this road and just past a layby, turn right onto a public footpath heading North East. After 50m pass a large wind turbine and then look out for the kissing gate on your left hand side that puts you into the adjacent field but travelling in the same direction. Follow the path around the edge of the field and then descend via a series of stiles to the town of Ringmer. In the town follow Springett Avenue until you arrive at a row of shops and then cut diagonally through the car park before crossing over the B2192 and following the path to the church. Pass through the churchyard and then follow Ham Lane out to the A26. Go straight over the A26 and continue straight on for 30m until you pick up a metalled road called Old Uckfield Lane. Turn right here and follow the road for 100m before taking a pubic footpath adjacent to a row of conifer trees off the left. Pass through 2 fields and then turn right on Wellingham Lane. Follow this road for 100m or so and then just after a right hand bend in the road and in amongst a small group of houses take a public footpath off to your left. Follow this for approx 700m
10
and this will bring you to Barcombe Mills Road. Turn left on the road for 100m and then take a right turn just after a public car park and head towards the mills themselves. Just before the first bridge take a right on a footpath and this is you on the Sussex Ouse Valley Way. Follow this path, crossing over the river on a footbridge after 1K, until you arrive at the Anchor Inn, the third feed station, at 38.5K.
OVER THE RIVER OUSE
Continue on the Sussex Ouse Valley Way for a further 3.5km before turning left on a footpath at 41K and heading towards a couple of farm houses. Circumnavigate the farm houses in an anti-clockwise direction and then continue on a footpath across a large field heading for a small wood in the distance. At the wood you will arrive at a metalled road called Sharpsbridge Lane, turn right here and follow the road for 2K, crossing over the River Ouse once more. On a right hand bend take the public footpath off to your left and follow this for 1K passing two fields before making your crossing of the A272. At the crossing take the left hand of the two driveways directly opposite which is also a public right of way, Follow this around the back of a house, cross a grass airstrip and pick up the obvious footpath that will take you through 3 fields and into the village of Fletching. Circle the cricket pitch and then turn left on the metalled road that will take you past the church and into the village high street. 200m up the high street on your right hand side is the village hall and your 4th feed station at 47.5K.
ONTO THE ASHDOWN FOREST
Head north out of the village for approximately 800m before coming to an offset crossroads where you head straight on up Bell Lane. After 500m turn right onto a track called Clapwater Lane that twists and turns before passing a group of houses and then turning into a footpath across fields for 800m. At Down Street turn right for 200m and then left onto Picketts Lane for 1K. At the A22 turn right for 100m and then immediately left onto Tylers Lane for 800m. At the next T-junction turn right onto Cackle Street and then after 100m follow the obvious track off to the left that leads you up onto the Ashdown Forest. After 100m pass through a gate
11
and then soon after take the left hand fork in the track and follow this path for 2.5K, keeping the large valley to your left as you ascend to Hollies Car Park. Once in the car park cross over Crowborough Road and then take the path off to the left keeping Ellison’s Pond on your right hand side. Head uphill to the prominent Camp Hill Clump at the top of the hill and then take your second left heading due north for a further 1K and passing through Bushy Willows Car Park. Cross over the B2026 and then head north for approx. 20m before taking the right hand fork in the paths and following this for a further 600m to Black Hill Car Park and the 5th Feed Station at 58K.
DOWN THE OLD RAILWAY LINE
Exit the car park and turn left for 20m on the B2188 before turning left and regaining the track heading north. Descend for 3K on a mix of tracks and paths before reaching a metalled road and a short and steep climb. At 61.5K you will come to a fork in the road, take the left hand fork and then pick up the footpath that handrails a driveway for approx. 300m. Back on the metalled road head due north for 2K before passing a church on your right hand side and descending steeply downhill to the Withyham Road. At the T-junction turn left for 30m crossing over a bridge and then take a footpath off to the right that heads in a straight line across two open fields. At the Hartfield Track (old railway line) take a right and follow this for 500m before turning left onto Beech Green Lane. Cross over the River Medway and head north for 500m uphill before turning right at a large pond just before 66K. Follow this track/ road for 1K due north until coming to a footpath that takes you to the right hand side of large barn. This footpath will become road again after a further 600m and lead you to a T-junction on the A264. Take a left here and head uphill for 500m before turning left down Ironchurch Lane (signposted to Blackham). A further 500m on this road will lead you to the 6th and final feed station at Blackham Church just over 69K.
TO THE FINISH LINE - FOR THE 50 MILER AND THE 34 MILER
Head west on Sussex Lane for 200m before turning right down a road that leads to a farm. Just before the entrance to the farm turn right on a footpath and then cross a railway
12
line at a pedestrian crossing point. Follow the footpath to the north and then keep a small valley on your left hand side as you continue to head north, passing over a couple of stiles and keeping a building on your left hand side. Join this building’s driveway to make Bassets Lane and turn left. After 30m take a right hand path and head steeply uphill into an open field. Pass through a series of fields, cross a minor road and then, after a further flat field turn right onto Rywell Road and follow this downhill to the Rock Inn. Continue down this road for 1.2K and then turn left onto a footpath. Follow this footpath for 300m before taking the right hand fork just after a kissing gate. You have approx. 6km to go from here and will be joining the marathon route that the full iron distance competitors are using so look out for some company! You’ll head up and over a farmer’s field and then pass the Chiddingstone Rec on your right before arriving at Chiddingstone High Street. Turn left here and head past the school and the pub before entering Chiddingstone Castle by the back gates. Run through the gardens of the castle before entering a wooded area on a wellmade track. Make your way up through a horse cross-country course before entering the grounds of Hever Castle via Park Wood. A circumnavigation of Hever Lake and a brief glimpse of the castle will see you to the finishing straight and the end of your epic run.

FUELLING & HYDRATION 50 MILE RUN
Failing to fuel and hydrate appropriately is a leading cause of underperformance in ultra marathons.
Your plan should focus on ensuring that you take in enough carbohydrate, fluid and sodium to fuel the work required and keep you hydrated. These are the 3 key elements of a solid fueling plan, everything else should be considered secondary to understanding and hitting these numbers.
BEFORE THE RACE
Fuel
What to do
Hydration
What to do
- Your race pack will include a packet of our strongest electrolyte drink, PH 1500
https://visit.pfandh.com/37Ve5vn
- Mix it into 500ml of water and aim to drink it about ~60-90 mins before you start
https://visit.pfandh.com/3upJC03
- This is known as ‘preloading’ and it can significantly improve your performance
- Finish your drink ~45 mins before you start to allow your gut to absorb it
- Drink the electrolytes in water you’d have drunk anyway so you don’t overdo it DON’T just drink lots of water before a race!
https://visit.pfandh.com/355YFU1
- Aim to carb load in the day or two before your event, to top off your stored energy (glycogen) levels
- Eat an energy gel in the final 15 mins or so before you start. This'll provide additional fuel to be utilised in the early stages and increase your focus and energy levels
Why?
- Carb-loading is a well-known tactic used by endurance athletes
- Think of your glycogen stores as the fuel you have in the tank before a long journey. The more you start with, the longer you can keep going before you need to top-up
- Simple carbs taken in the last 15 mins will hit your bloodstream around the start of the race, increasing energy availability just as energy use is ramping up in your body
- You can end up diluting your blood sodium levels, increasing the risk of a race-ruining condition called hyponatremia (low blood sodium levels)
Why?
https://visit.pfandh.com/3JCCmnM
- It’ll boost your blood volume, a proven way to enhance performance during intense exercise, especially in the heat
- It’ll help your cardiovascular system cool you down and deliver oxygen to your working muscles. This reduces fatigue and enables you to maintain your performance for longer
https://visit.pfandh.com/37Ve5vn
- PH 1500 electrolyte drink is a very effective preloader as it contains 3x more sodium than typical sports drinks
- Preloading may also help you avoid cramp, which can be triggered by sodium depletion

DURING THE RACE Fuel
What fuel is available at the feed stations?
- An hourly intake of ~60-90+ grams per hour is not something all athletes can achieve immediately and it can take a bit of time to build up to this rate of consumption, especially if you’ve been prone to suffering from GI issues in the past
https://www.precisionhydration.com/products/pf-30-gel/
- PF 30 Energy Gels. Each gel contains 30g of carbohydrate
Why?
https://www.precisionhydration.com/products/pf-30-chew/
- PF 30 Energy Chews, a mixture of Original and Mint & Lemon flavours. Each packet contains 30g of carbohydrate, delivered as 2 x 15g chews
- A selection of food and drink such as bananas (cut into thirds, about 9g of carb per third), flat coca-cola (about 10g of carb per 100ml) and jelly babies (or similar, about 5g of carb per sweet)
What to do
- When it comes to powering high intensity endurance exercise, carbohydrate is the main source of fuel used by your body
- Glycogen (stored carbohydrate) is a finite resource. 90-120 minutes of hard activity will generally deplete your stores enough to significantly compromise your performance. So, at some point, taking in carbs is necessary to maintain a high level of performance
Pro tips
https://www.precisionhydration.com/products/precision-fuel-sample-pack/#thecarbcalculator
- Use our Quick Carb Calculator to get an idea of how much carbohydrate you'll need per hour to perform at your best
- Select 'Run' as your sport to get advice best suited to running
- Depending on how long you're going to be running for and your intensity, you're going to benefit from some form of carbohydrate ingestion (~30-60g carb per hour)
- Some athletes racing a marathon will benefit from higher intakes of 60 to 90 grams of carbohydrate per hour, perhaps even more than 90g, as long as the amount consumed doesn’t cause stomach problems
- The higher the amount of carbohydrate you’re aiming to ingest, the more crucial ‘training your gut’ in the lead up to your race becomes
- Carry your own fuel on the second run if possible. Gels/chews weigh very little and this approach allows you to use some you’ve properly tested in training. It also means you won’t accidentally miss picking one at a busy feed station and can eat them whenever you like
- Generally speaking, the more energy you can consume in the early stages of the run, the stronger you’ll be able to finish, so don’t restrict your carb intake if you’re tolerating it well
Hydration
What hydration products are available at the feed stations?
https://www.precisionhydration.com/products/ph-1000-low-calorie-electrolyte-supplement/ https://visit.pfandh.com/3itxJRh
- PH 1000, a low-carb electrolyte drink containing 1,000mg of sodium per litre (~2x sodium found in typical sports drinks)
- Water
25
www.precisionfuelandhydration.com/castle LEARN MORE AT PRECISIONFUELANDHYDRATION.COM/CASTLE
What to do
- An ultra marathon is too long to go without drinking, so you’re going to need to be knocking back a reasonable amount of fluids and electrolytes during the run
- The aim is to try to avoid under-drinking to the point that dehydration hampers your performance, whilst avoiding over-drinking, which can lead to hyponatremia (low blood sodium levels)
- During a 50-miler, you need to make a conscious effort to stay on top of your fluid and electrolyte replacement throughout to avoid dehydration derailing your race later on
- Most athletes will need to take in between 300ml and 750ml per hour during the race. The exact amount depends on the conditions, your own sweat rate and past experiences
- Experimenting within these guidelines, whilst learning to listen to your body, is the best way to work out how much you need to drink during a race
- On the day, factors such as your pace and the weather will influence what you actually need and you should adjust your intake according to how you feel as the race unfolds
Why
- Taking on board an appropriate amount of fluid and electrolytes is essential to maintaining your blood volume and supporting the cardiovascular effort you’ll be putting in
- Hydration is, of course, particularly important during longer events, when your net sweat losses can really mount up. That's especially the case if it'll be hot on the day
Pro tips
https://www.sciencedaily.com/releases/2015/03/150304075220.htm
- Drinking from cups at feed stations can make it tricky to work out exactly how much fluid you’re consuming. As a rough guide, half a standard paper cup will give you ~100ml of water
- Squeeze aid station cups across the top to form a slit to pour water out of. This’ll reduce the amount that gets spilled
- It’s often faster overall to walk a few paces through feed stations to ensure you get enough fluids on board, rather than trying to drink from cups whilst running at full speed
https://visit.pfandh.com/3NgnhKY
- Consider carrying some blister-packed Electrolyte Capsules. Swallowing 2 capsules per 500ml of water you consume would deliver the same ratio of electrolytes to fluid as a bottle of PH 1000 from the feed stations
TRY THE ON-COURSE FUEL/HYDRATION IN TRAINING
"Nothing new on race day" has always been solid advice.
https://visit.pfandh.com/3iz4IDH
Grab a Castle Race Series Taster
- A 2015 study found that athletes who adequately replaced the sodium lost in their sweat finished a middle distance triathlon an average of 26 minutes faster than those who didn’t
https://www.sciencedaily.com/releases/2015/03/150304075220.htm
Pack to thoroughly road-test the on-course fuel and hydration before your race.
Don't forget to use the code CASTLE to get 15% off your first order.
- As well as maintaining fluid balance, sodium plays an important role in the absorption of nutrients in the gut, maintaining cognitive function, nerve impulse transmission and in muscle contraction www.precisionfuelandhydration.com/castle
