Thanks!
I think the main reason for the falling avg mph is more that the two days I had 12 and 12.5 mph the wind was almost always at my back. I think my comfort zone right now is the 10-11 mph. I plan on sticking to 5-6 days a week with 3 days of 13-15 miles and the rest 6-10 mile rides for the next couple of weeks as my body gets used to the work and to give myself a chance to build up stamina. I need to focus on my cadence since I have a tendency to peddle and coast vs a continuous peddle. Any tips on getting used to a lower gear and higher cadence? I find myself not liking the lack of resistance from the pedals.
