Hi everyone. I wonder if you can help. I completed my first ever GNR on Sunday - in 2hrs 12mins which I was really pleased about - but my trainers were getting worn out so I got a big blister on the side of my right foot. Yesterday my feet ached a little bit but today my right foot has really swollen up and I'm limping around quite badly. Can anyone recommend anything or do I just need to wait for the swelling to go down?
