Some useful notes from Australian Sprint Cycling Coach

I'm not a qualified coach but you could easily train to get more endurance though. i'm a skinny racing snake that can't sprint but can ride at a decent pace for an hour or 2 but find long distances a problem as i find it hard to eat while riding and will bonk after a while. if i actually bothered to do longer rides and more intervals/short efforts i would improve these areas. still wouldn't be a sprinter or 100miles a day rider but specific training would see an improvement.

More endurance yes, and compared to joe public I had an amazing amount, but not in any way similar to someone who's body was more naturally set up for endurance doing the exact same training.

If you are naturally better at one thing than another, then make use of that, and don't expect to be something you are not.
