Every week Station Routine Orders would be published, amongst them were often adventurous training activities: sailing in Gosport; biking in Peru; skiing in Bavaria; skydiving in Wiltshire, all this on top of other sports tours like hockey around Germany. Usually there is a personal contribution, but for instance I did a £1000 freefall course for less than £300 - a lot was a lot cheaper. If you're young and fit, I'd thoroughly recommend it to you.
