I am fortunate enough to get an hour for lunch. So I get some good riding in; usually 15-18 miles, depending on the route. The downside is that it is in Reisterstown, not know for cycling friendly roads and at times-motorists. Today was a race pace effort. 14.4 miles, 18.1 avg. speed, 194 max hr/171 avg. 1200+ feet of vert on my Lemond Poprad with cyclocross tires. Total time was 47:02. Temperature was a cool 98°.
