Time Trial / Time Trialling / TT

I'm up for doing the 24 next year and I've never done a single TT in my life, and no plans to do any before the 24.

I have done some long distance riding though, so I'll know I'll be fine (especially mentally) with something as short(!) as a 24.

Quoted, you can't go back on it now.

Ha! Epic fail. Nowhere near it. I've done a single 200km Audax this year and one other ride over 100km.
