Well I did a trails halfie yesterday and now I'm sore, but not too sore. Came 8th out of 20 males, and it seemed like there was a big gap (nearly 20 minutes) between be and the guys in front so my theory is that they were all the good runners and I was best of the rest.
Not too bad, but it was really really tough going at only the 17km mark on a fairly gentle uphill slope, so lots of work to do to build up to 56kms
