my local parkrun group are going to try 8 parkrun courses in a day (1st at 07:30, last at 19:00). Of course I can't do that. I did parkrun twice by accident a couple of week ago, so I'm gonna try for 3 with a smaller group of slower runners. I'm going to try extending my long runs (currently 10k) a bit and maybe I can attempt 4? Or is that pushing it a bit? target date is 5th September. I have a 5k run the week after and a 10k the week after that.
