DalesRunner 40

7th September 2024
Semerwater and Wensleydale

The DR40 is the final and longest race of the series. Run over less technical terrain than the first two races in the series, but with over 3,000ft of ascent, this is still a challenging event. Covering a markedly longer distance – requiring strategy, consistency and stamina – the course features good hard-packed trail (Roman Road) and less technical descending, but one steady climb runs to almost 12km!

Course Summary

Distance: 42km / 26.2m (roughly)

The race starts with a long hill running up towards Stalling Busk and then onto a cracking trail over the Stake. On the far side of the Stake, you drop down towards Cray with a minor diversion taking you round the foot of Buckden Pike and then on past the White Lion at Cray.

Here you contour round Slades and into the Langstrothdale valley with some cracking meadows to pass through until you pass Yockenthwaite and drop onto the Dales Way. Following the Dales Way will take you past Beckermonds, Oughtershaw, Nethergill and Swarthgill then you'll hit a great section through fell and field towards Cam Houses and the Cam High Road which you will stay on as you head back towards Semerwater.

Just before dropping back into Semerwater, you get taken on a detour round Drumaldrace and Weather fell offering great views over Hawes and then you approach the lake with a fast flowing descent for the finish.

Shoe Recommendation: Trail shoe, there are a few boggy sections but more on hard track or tarmac.

The race course will be well marked with orange barrier tape as well as orange pin flags, trail junctions and turns will be well marked with coloured arrow signs to show you the way. All critical turns and road crossings will be manned by our marshals so you are going to have to try pretty hard to go wrong but be aware that course markings can be moved or stolen and for this reason we strongly advise carrying a copy of the route map.

Marshals will be happy to support you in refilling bottles and we advise you to consider carrying a collapsible/soft cup. Water will also be available at the finish.

Runners & Rubbish

Please respect the trails and the beauty of the dales by disposing of any rubbish at one of our aid stations or take it home with you.

Code of conduct

Be polite to our marshals, first aiders and members of staff, these people are volunteering their free time to assist you in reaching the finish line and are doing everything they can to get you there.

Do not rely on marshals, photographers or other staff persons to direct you on your course. It is YOUR responsibility to know your course and follow the course signs.

Remember to always remain on the designated marked trails, no short cutting.

Poles are allowed (but probably not necessary), please be conscious of where you’re pointing them.

This course includes single track. If you are attempting to pass, please alert the runner in front of you before flying past them. Likewise, if you hear a runner approaching you from behind, attempt to find a spot to allow the runner to pass.

As a general rule, when passing a runner, announce, 'on your left'.

Uphill runners/hikers have the right of way to downhill runners. Remain in control as you descend and respect the other runners.

Everyone is after the same goal here so let’s be respectful of each other’s races and have fun.


You will register in the car park at Semerwater. We may be performing kit spot checks at registration or somewhere on the course, anyone failing to have the mandatory kit will be disqualified.
