Meant to do this hilly loop I had done a while back 6 times with 2 minutes rest each time. The loop usually takes about 9:30 and most of the trails were complete mud today so quite tough going.
Legs were tired starting, but I started conservatively and ran the first fine, slowed down a bit on the next, and then on the third I felt like I was hardly running. My hamstrings were sore and my legs just wouldn't move so called it there.
The last 3 days have been pretty easy so I'm not too sure what happened there. My legs didn't feel sore after working out yesterday, but it's really the only thing it can be. My legs are usually fine working out before running, but should I avoid going to the gym before more physical orienteering/running sessions?
