Quitting Coffee – Is it worth it?

'A ride without a café stop is like a bike without wheels', a statement from Geraint Thomas which I couldn't agree with more. One of the many things I found interesting in his book, The World of Cycling According to G, was how he talked about quitting caffeine 2-3 weeks before a big race. As someone looking for all the marginal gains he can get it got me thinking about why he might do this and how it could help me?
