Cycling UK Forum

I cycle with a friend of mine a lot, and we're pretty dead even when it comes to riding. However he just randomly decided to go for a run, which is not something he does regularly, and he was waaaaay faster than anything I could do.

What could be the reason for this? It's seems like both cycling and running work similar areas, so why is he so different?

Maybe this belongs in ask science or something?

I'm just starting to tinker around with bike repair and don't really know what tools to get. Since I'm on a bit of a tight budget and would most likely be buying tools over a long period of time what are some of the essential must haves i need to get first?
