Achilles heel injury - ouch!
I went for an early morning run with a couple of friends this morning. They run marathons and I don’t - so it was always going to be fun 
Anyway - they were realy good and I was having a great run, various hills, new route, gorgeous morning! After around 30 minutes I could start to feel a dull ache in my achilles tendon. It got progressively more sore over the next 10-15 minutes and I had to call a halt to the run. To be honest, I was only planning on a 45 minute run anyway so the time and the pace was perfect. My breathing was just fine so I should be easily OK to do the 10K in 4 weeks.
I got home and put ice on it for 20 minutes but it has been stiff and tender for most of the day. I’ll try to rest it as much as possible and re-ice it tonight. Hopefully it should be a problem. It may be a sign that I need new trainers (I’ve been thinking that for a few weeks anyway).
I’m doing upper body training tomorrow so I should still be able to rest OK.
Cheers, Mark
