Running

No, that's great, I appreciate the tips. The pain now, as I sit at my desk, is a 2. A couple of days ago when I did to do a mile or so on the treadmill, it got to 7 and I had to stop. Then it hurt all yesterday, to the point that going down stairs made me wince. I think I'll try to do some stretches at home, cycle to and from work and go back to Parkrun the Saturday after this one to see how I get on.

Running uses a lot of muscles, cycling doesnt. Personaly I'd keep going, but prepare myself to quit early if I did'nt like the feeling.

If you are running on asfalt, you will be attempting to dampen your stride using muscles in the lower leg. Try running off road. The variation in stride due to terrain also helps to reduce strain.
