I'm not a huge fan of hot weather but 2013 and 2012 have been years where my schedule has forced me to begin my ultra running race season in the summer rather than the spring. I did a 31 mile race last August when it was 85* at 0600 and that just sucks! I find that being outside a lot year round helps me acclimate better as the seasons change, but I have a 50k in 4 weeks and a 50 miler the last weekend of August and I'm getting a little nervous about both. In that kind of weather it is impossible to stay ahead of your hydration needs and so you just try to negate the deficit as much as possible. Virginia is weird because we get can get a good amount of snow in the winter and be in the 20s for weeks, but come summertime we roll right into the upper 90s with a sticky type of humidity.
