I don't think the two things are related, but the extra protein may have helped! I hadn't run for a week due to the heat, but it's cooled down today so I went out this morning.
Got to 8k, it was still hot and I have an ongoing blister problem - it heals between runs then starts to hurt again around the 2k mark. I now run wearing a blister plaster. I'm thinking of trying twin skin socks, does anyone have any experience of them? Or maybe I should get new shoes as it's where the upper meets the sole. But my Brooks adrenaline are so comfy otherwise!
I can't believe that I've been running for nearly a year now and haven't swallowed a fly before now! Yuk! I'm glad I was carrying water this morning! 😄
