Mine is from Frisco to the Galleria area in Dallas, about 40 miles round trip. Mornings aren't a big deal since it's still cool enough, and as long as you're moving and getting some air flow, the afternoons aren't bad either, even when it's 100+. I take one bottle of ice water before I leave work and it's plenty. You might feel like you're being cooked alive if you have to stop at a light or have to go real slow, but other than that, no problems.
