Racing an ultra in winter
Winter ultras reward preparation. Short days mean more hours by head torch, and wet ground slows everyone down. Mandatory kit lists tend to be longer, with spare warm layers, waterproofs and sometimes a bivvy bag, and they are there for good reason.
Plan for slower splits than a summer race and check your margins with the ultra pace calculator. New to the distance? Start with our first ultramarathon guide.
