Agree on getting out there. Today rode 64 miles averaging 16.8+ and turn 69 tomorrow. Been riding over two years on a road bike.

First fitting, new bike and first time trainer all worth at least one MPH although 15 to 20 MPH winds so think worth more.

As for century, I rode 70 before doing but was doing regular 45 to 55 before which gave the foundation

Let us know how you do.
