Before the Big Race

My bike, before the big race tomorrow. The swim is the scariest element, by far, but the bike is somehow the biggest variable for me because it's a huge piece of mechanical equipment that I am relying on. Coming to this sport as a runner, I am used to only having to rely on myself and my body. There's very little that can happen that would mean I couldn't run my race. Shoes? Check. That's what I am used to. Now I have this thing to worry about - with its own quirks and issues and personality.
