What do the letters A B C D E mean by a race?

E = Everyone

And, measured by your sustainable power in watts (FTP) per kilogram of weight

  • A = strongest riders
  • B, C & D = most of us

D is generally up to 2.5 w/kg, C is up to 3.2 …

It’s an indicator of what effort and cycling strength will be expected for that event.
