I've been running for a few months now but am still quite new and slow - I run 2-3 times a week including at least 1 5k, but that takes me about 38mins so not very quick. Yesterday I did a new exercise class (legs, bums and tums) and my muscles are a bit sore today - particularly my quads. Would it be really stupid to do parkrun today, or could I do it and just accept I might be even slower than normal?
If it makes a difference, I also have a kickboxing grading later, which will involve some stamina tests, although I'm wondering if the parkrun might actually be a good warm up/muscle stretch for the grading...
