I have recently taken up cycling after 20 odd years. I go out riding twice a week and since I live in cheshire in a valley any which way I go there are hills! I dont mind this as the views from the top are awesome. The only problem is, I see other cyclists tootling up the hills, where I have to stop every half a mile or so, less if it is a big hill! One excuse I have is I take my SLR camera with me every time so I have a quite heavy rucksack!! Any tips?
