If I run long distances my back starts to ache towards the end ThursdayLast but usually 10 miles plus. I assume it's just being on my feet that long and perhaps not great running posture.
Hi ihaveadirtydog! I have a garmin 110, it doesn't have loads of functions but tells you time, distance and pace as well as beeping and telling pace per lap (which I set to a mile).
I always recommend karrimor sirzy, last well and start at £9.99 from sports direct.
A week will be ok DhamaLovesDraco, give parkrun a go tomorrow if you feel ok but Sunday will definitely be fine.
