Just got back from a cycling weekend up in the mountains. Saturday was 91 miles and 5K climbing at a good pace (up to 785 VAM). Sunday was a more tame 53 miles and 2.3K. I was strong - stronger than I expected given I have been focused on shorter, high-intensity rides. I was huffing and puffing from the altitude (averaged about 7,500'), but the legs responded whenever I needed them. Great fun with friends: riding, then eating and watching the tour. You know it's a different sort of group when the Friday evening BBQ has no beer, but includes an IV hydration drip for one of the guys, with the bag tied to a light fixture above the dinner table.
