Notes
Garmin had it at 42.7km. 1:44:47 at the half, which means about 1:50 for the second half.
Warm and extremely humid throughout.
Felt real good going through the half, but I think that led me to push it a bit harder than I should have -- all the 4:50ish kms were probably a bit overreaching. Anyways, I paid with a pretty awful and unpleasant last 8km. Overall happy with the final time, just wish I had even paced it a bit more (probably could have shaved a couple minutes off if I'd done that).
