Just 10 miles for me today. The 5 miles to the site took about 40 minutes. 68 year old cancer survivor with a bad knee, and riding my single speed flat bar roadbike. A number of hills, headwinds, short walk of shame, a couple quick stops for some water. This, for our weekly group I call the Chess Geezers. But, that ride home! Lots of downhill rifing, and the same route takes just 15 minutes. Fun as can be, like an amusement park ride. Both hubs are nicely greased, so it glides really well. FUN!!!!
