81 km/50 mi
This was pretty much the worst day so far. I'd worried about the hills, but for the most part they were no worse than eastern Kansas. But the wind—I found out later we're talking about 15 to 30 miles per hour—just killed me. I'm sick of wind! I'd like to actually start enjoying these rides, but I've had ridiculous winds EVERY DAY but one. After days of going south into south winds, when I headed north to Black Mesa, it switched for me! How pleasant!
