Had a good cross race over in the south west today, until i started getting really bad back pain and had to pull out a lap from the end, I've not had the problem before, my position on the bike feels good although I could be a little more stretched out. saddle to bar drop is a tad less than my other bikes as is normal in cross. any ideas what could be causing this? bad fit, or lack of core strength or something?
I find that I get a sore back in the first two or three really muddy races, I think because you're working harder for longer and not getting any respite. If you can, it's worth simulating a race on a muddy course a few times to help the body adjust.
