I completed my 2nd Mtb marathon at the weekend. It was 8 hours, complete as many laps as you could in the 8 hours.
By about lap 4/5 my legs were screaming on the descents, I was actually looking forward to the climbs to give my legs a break from the pain. I took a skills course a few months ago which covered position on the bike so thought I was positioned correctly, as I was new to mountain biking at the start of the year. I was on my trek hard tail, with a dropper fitted. I didn’t have a dropper in my first event so was obviously using the saddle to support me while descending.
Is there something I can do to train for this? Or am I positioned wrong? Just not strong enough? Or will it just come with time?
