Best post I've seen on UKC for ages- great to hear some enthusiasm. Ignore the rubbish some can't help but post, there's some good stuff on here too.
Firsly, you'll need a basic set of equipment- in this order- climbing shoes, harness, HMS caribiner & belay device, chalk bag.
There's oodles more gear you may end up wanting after that- but on the assumption you're climbing with someone who knows what they're doing then they should be able to share theirs with you in the short term- esp a rope.
In terms of finding someone to climb with, Options-
1) Join a club- I totally get that you're not interested in a climbing wall, but tbh that's where most clubs do their regular meets these days. It's probably the best place to meet other climbers- though be warned, a lot of them won't share your interest in the outdoors. Still- recommended. A lot of the more traditional clubs also own huts in various parts of the country- which are usually much nicer than the word hut might suggest- where accomodation will cost around £5-10/ night, so the cost of going climbing canget brought down that way.
2) Put a post for a climbing partner on here. Explain yourself- your level of experience, the equipment you own, where you might like to go, your travel facilities, your aspirations, etc. You may well find you can hook up with someone useful. Don't forget that you can go climbing on a daytrip from Cheltenham- to the Lower Wye Valley (the Forest of Dean, Chepstow area) or to the Bristol area (Avon Gorge by the Clifton Suspension bridge for example) You can actually climb (it's limited in some respects) at Cleeve Hill above Cheltenham.
3) Ummm... On that last one, I'm guessing you're a 28yr old lady. Sometimes 28y old ladies prefer (for a whole load of valid reasons) to climb with other ladies. I'll suggest to my girlfriend that after her triathlon, in a couple of weeks, when she wants to do a little climbing, that she drops you a note. She 'knows the ropes' so might work out to be a good day out. We're between the Forest of Dean and Birmingham at the moment, so Cheltenham is in the ball park.
