Well, yeah I have, but it was a summer storm. In fact it was a THUNDERSTORM! I remember asking at the registration tent if the race was going to go on as planned despite the thunder and lightning and I remember the chick sayiing "oh YEAH. It just gives you more reason to swim and ride faster"!
But SNOW?? Ummm. No.. I would imagine that the transistions are going to be really slow as you'll need to bundle up. But I'd rather take extra time in the name of warmth..
Do you have tires that have some good tread on them? I'm sure you do seeing as where you live. I'd say just good solid tires and running shoes w/ lots of hearty tread is all you can really do.
Wow! A whole other twist on triathlon that's for sure! But almost sounds fun?? Remember the harder the race the more bragging rights you'll have at the end! Go out there and tear it up!!
