Very impressive gains in speed! What is even more impressive is that you are doing this on a Hybrid with straight bars and not drop bars. I bet most of the fast crowd rides road bikes right? I know that I ride about 3 MPH faster on my road bike than on my hybrid with the same effort. If I go to the drops I can usually ride an extra 1 MPH. Just think of how much extra effort you put into keep up with the fast crowd!!!

It must be very rewarding to feel your body progressing and being able to measure that improvement so clearly. Keep up the amazing work.

Enjoy the ride,
