Talking to colleagues about RA
I work in the marketing team at the Forestry Commission and a big part of my role is promoting our mountain biking trails. My colleagues are really keen to get me out on a bike and ride the trails with them. I have RA which is particularly bad in my wrists, and although I can (and enjoy) riding a bike, I ride at a gentle leisurely pace and I am really worried about going for a ride with my colleagues who don't know about my condition.
I'm looking for some advice on how to tell colleagues about RA. I'm 29 and generally fit so looking at me you wouldn't know I had RA, and I don't want to change their perspective of me. Should I just make up an excuse of why I can't ride with them or should I be honest? Thanks in advance for any advice.
