I've been known to turn up drunk at triathlons and do very well. I'm more of a heat-of-the-moment type of guy. A friend will tell me about something coming up, maybe that weekend, and usually not an abundance of thought goes into my doing it. ↗
I'm not a big fan of the gym, I do lots of outdoor aerobics - yoga, swimming, running - but I kinda hate talking about it. We have a term in Australia, it makes you sound like a wanker. ↗
I drink protein shakes nonstop - three or four a day - and I run a lot, so you get rid of the bad carbs and keep the rest so you have the energy to make it through. ↗
