I went for a bike ride today - I want to get back into exercising, somehow, and I don't quite feel up to running. I can't believe I haven't thought of this before - it was brilliant! I went along a bridleway-type path in a park near here (along the railway). Here's a map, assuming it works this time:
I even found a load of blackberries by the side of the path, next to the railway viaduct. Tasty!
