Yes. I'm running. I had heard that the courses aren't all 10k. I should double check the Stevenage one is although I'm sure they did announce it was and my watch said 6.3 miles. I'm having it anyway.
I think if I can do the Triffic Trail in under 50mins this year I'll call that job done. The PBs are "nice to haves" what I'm looking for is consistently under 50. Running consistently at 7:30 over that kind of distance is my next target.
