It really depends what you mean by "opportunities". In the UK, really, once you get to 16+, you're looking at doing gym recreationally, for fun, masters, or elite.
So for example if P+F is 17 and considering her choices;
1) She's elite. She continues training elite and maybe finds a uni she can attend part time around her gym schedule.
2) She wants to keep training regional/grades/challenge, and attend Uni/get a job. She finds a club and continues to train as she has always done, just swapping school for Uni. Problem with this is uni or work hours rarely finish up at 3.30, so it can be tricky scheduling training around "real" life.
3) She knocks it right back, and finds a club to do adult sessions, or sets up/joins a uni club. These are usually inclusive, as you say, with other students coaching, so it will be for fun mainly, possibly a masters or BUSA comp occasionally. But as Lucy says, tramp clubs are far more common, mainly because a couple of tramps is easy to set out and store, gymnastics equipment is expensive and space taking. So few uni's can provide gymnastics facilities, unless they can liaise with a local club for gym time or are one of the lucky ones like L'bro.
I suppose there is one other option, in that she looks at it as a career to earn money from. So coaching, professional jobs as an acrobat or circus etc. It is possible to make a living, even a good one, or work it around uni/temp jobs.
Or just thought of another one :lol:, take all that gymnastics experience and find another sport to excel at- pole vaulting, long/high jump, cycling, rowing…There's a big ad out from british canoeing at the moment- 15+ girls at regional level in any sport, or 18+ competing at a national level. They'd have her arm off :lol:
O/t but Lucy, did you know east london gym have a lot of adult sessions in the day- I suppose to bring in money when there are no kids. I think they used to be "open gym" style, but I'm sure I read recently they're starting more coached sessions…
