So I now haven't been able to run since last Sunday when I did a 10k race.
I think the problem is that I normally run off road and the race I did was a road race.
I think I've developed plantar facitiis as the pain is in the very bottom of my heal.
I've been trying to keep off it but had to do a lot of walking for work today and was limping again by this evening.
I think I'm going to go to the doctors tomorrow and see what they say.
Although I will find it amusing to tell them how I did it as last time I was there I got told I was obese and needed to loose some weight which is the boot up the arse I needed to get into running in the first place!
