ACG, I hope that you are seeing a doctor about your recurring UTIs. And that you are perhaps getting prevention tips from your doctor, including potentially an antibiotic to take if you feel an infection coming on or know that an activity you participated in has put you at very high risk of one.
When I was getting recurring UTIs, I took cranberry pills as well as drinking cranberry juice, as well as tons of water, and daily multivitamins as well. I can't really imagine running (and especially not cycling!) while experiencing the pain and discomfort of a UTI, but I suppose I might be able to handle it if I took Azo to help with the pain. And only if I could deal with the great kool-aid colored stains in my underwear..
“Hope is the thing with feathers, that perches in the soul, and sings the tune without words, and never stops at all.”
