In reply to johnSD:
Just checked the form again to be sure.
It asks if you are involved in any activities such as:
* Diving (other than as a holiday activity), caving or potholing
* Climbing outside of the UK
* Extreme sports (for example, base jumping, bungee jumping, white water rafting)
* Flying (including hang gliding, microlighting, parachuting, etc)
* Motor car or bike racing on a racing circuit
And doesn't mind at all if you only climb in the UK
