Knowing how crafty adventure racers can be, I've stopped posting my training log since I started doing final testing on the STORM the Eastern Shore Adventure Race course a few weeks ago. If people notice I have a lot of "6 hour paddles" for example, that would tip them off to a rather long paddling leg at the race. Same thing if I say "4 hour night bike." After the race, I'll resume. The whole training log thing is mostly for my personal benefit so I can reflect on my progress over time. I might start adding mileage to my training log, but I'm a big believer in getting the time under load numbers and not obsessing with precise distances.
STORM racers, by the way, should brace for multiple legs of the same discipline instead of just one long trek, one long bike, and one long paddle (it's unlikely, for example, that you'll have a 6 hour paddle unless you plan to go all the way across the Chesapeake Bay -- which reminds me about a subject for another post alogether). We designed the race with disciplines interspersed so that racers get some variety and we keep the support crews busy!
