Blues

I regularly ride several hilly road routes with very few flat areas. I ride with one of three single speeds or 4 geared bikes. The single speeds all have a little different gearing, chosen especially for my routes. For all rides, I try and keep my heart rate mostly in Zone 3 with some Zone 4 at the top of the hills. My HR efforts are fairly consistent as per my Polar watch. My average speeds are amazingly close with the extreme ranges within about 10% over the last 50 rides. Without doing a bunch of data analysis, the geared bikes might have a little advantage. I was surprised the SSs performed so well. Since they don't seem to have much if any penalty, I ride them a lot. There's something enticing about riding a SS. --Fred
