Good idea. If you get too hot, have a read of https://www.ukclimbing.com/forums/running/fell_race_waterproof_recommendations-613849
Yeah, everything costs a fortune which is the issue!
Decathlon is looking the best at the moment at £35 for some trousers
Sounds like it should.
Crap, just remembered my running jacket isn't particularly waterproof either, it's only windproof So just bought a new one.
It would've been cheaper to just pull out of the race!
Also eyeing this up, it's very cheap for a longer run and be good practice for the Lakeland 50. @Dup this seems right up your street!
