Didn't remember to start my data logger until about 15 minutes in, so this was a 16 mile plus day of mountain biking. How, I don't really know, because I haven't mountain biked since my trip to Pisgah other than one little ride that wasn't even three miles long last week. But I actually seemed to last okay on this day, so that's good. You can click here for the full gory details of the data, but the map pictured here shows the route, too. This isn't even all of the trail available in Chapel Hill near the airport.
