I’ve done it, I’ve managed to refrain from consuming caffeine (except for in some chocolate I’ve eaten) for just over two weeks before the marathon.
Now I’ve got my rocket fuel ready for race day: pro plus (1 or 2 taken before), caffeine sis gels (5 for during – 1 spare, I’ll maybe only take 4) and some chocolate covered coffee beans to boot if I fancy them.
Studies have shown that caffeine can help performance, and it works best in people who take it regularly, then have a drought of it for around 2 weeks. 🙂
I’m looking forward to seeing what the outcome will be. (Although I might reconsider taking the pro plus Incase I get jittery!)
