Hi I'm Katy
I live In Basingstoke, as Q said I'm actively trying to get meets going round the North Hants / Berkshire area. There also Rawk she based In Newbury
I might doing a meet in Basingstoke next weekend too, you're welcome to join us.
erm,,,Learning flips you really need a gym...I would suggest going to Basingstoke Gymnasium, when there doing Parkour sessions. There have trainers there that can advise on technique and equipment trampolines, crash mats, foam pit, bouncy flooring etc..
Once you master somersaults on two legs you stand a better chance with stilts strapped on.
