If you want to be a BC coach previous experience does not count
level 1 (don’t bother)
Level 2 Go-ride lets you coach groups of novice riders in a non specific environment (not a track, not on any technical/ hard off-road, not on the open road). No 1:1 coaching
Level 2 discipline specific is for groups in a specific environment (road and track and BMX only available, MTB XC next year (it was next year three years ago)). No 1:1 coaching
Level 3 lets you coach 1:1, track and road only available
Level 4 doesn’t exist
level 2 is generally easy, the pain is getting the sessions you need to qualify and the paperwork
ABCC is different but most of them cross qualify
you need to join one or the other or both to get cheap decent insurance and BC will do a CRB for you as well. BC donot recognise ABCC qualifications
BC are lauching a “ride leader” qualification with Sky for leading road rides this summer, its free and you get paid for the rides (see the BC website)
