Hey bro, whatever you do, don't tell Ric, 2LAP, or Maarten that you have found an endurance activity that packs on leg muscle!!! It can't happen in their world!!! Sounds like you have been able to do the same with your bike!!!
If you like to ride do that. Blading is a lower form of sport. If you still want to blade, be sure to "check six" (look behind you) when skating over everybody's line!!!
