I'm sitting here with furrowed brow because Liz did some of France's most infamous climbs after three weeks of riding and I'm worried about my weeklong tour of Middle Tennessee. Granted, repeated steep grades, no matter how short, can take it out of you, but still. Alpe d'Huez? Five hundred miles in 10 days? I must be a big wimp or something. The first time I hit 500 miles in a month was a big deal. Am I missing something?
