I have a couple of friends who cycle a lot. By that I mean all school day on their days off work (work part time) plus at least 2 evenings and a large proportion of the weekend. I get the importance of exercise and I do and also have friends who do a few 5k runs a week but never mention it. I wouldn't mind if they would keep it to themselves, but they seem to have the knack of turning conversation around so they can talk about their bike ride, they moan about how tired and achey they are. They complain their dh's (who work full time) are not pulling their weight (dispite the fact they are spending a couple of days sat on their bikes). And their latest feats are all posted on social media. I just get the feeling they think it's great and the rest of the world is missing out when in reality non excessive excercisers just think it's a bit sad and they need to get a life.
