Not sure I was going to make it home today, it was bloody hot. Overnight low was 81 and it was 82 when I left at 0715 with no wind and high humidity. Had to climb Newport Coast at mile 40, hot but doable. But the last five miles were tough. Ran out of water with 2 miles to go, drank two bottles in 16 miles, probably should have had another Nuun along as I finished the first Nuun bottle before the break so just water after that. Don't think it was a calorie deficit bonk, had my normal cereal and banana for breakfast and a Clif bar at the break which is typical.
HR would recover fairly quickly to below 120 when I stopped, but even modest exertion would see it back into the upper 140s very quickly. Absolute temperatures were higher yesterday but there was a breeze and much less humidity, so did not affect me as much.
We had a guest rider from Miami, he thought it was a nice day!
