Welcome ironwoman!
It's incouraging to find people who are so active and have UC! I've always wanted to train for a 10K but after being diagnose you kinda loose the sense of "what can I still do". Guess we can't live our lives in a "glass house".
I just started back to exercising and taking karate. It's a bit of a change as I can't take Advil for pain! I'm also trying to make sense out of what can't be made sense of! Been doing fine then BANG....UC comes back. Sometimes I wonder if it worst taking all the pills, especially if the side effects are wrost than the UC!
Anyway, hang in there and don't give up on your dreams! It gets fustrating at times, but this is how we learn to adopt to change and "go with the flow". Life is to short and we all need to find things that make us feel complete.
The best advise I can give is not to go crazy trying to change things. Try to learn how to adopt and be positive that a flare it's a temporary point in our lives. There's so much we can still do with or without a flare! Just need to find that combo
