Hi, I'm a brand new beginner in cycling, only 2 weeks into it, and new to the forum. I have not rode this past week due to my right knee hurting. I bought my bike on November 10th and road it through that week getting used to everything, especially clipping in. During that week, the most miles I put on the bike at one time was 10 and until that Saturday, November 17, I had probably a total of 25. On the 17th, I rode with a local group for 35 miles which is 3x as much as I had done in one ride. Towards the end of my ride I noticed my knee starting to hurt. For a few days it was actually painful when I walked. But as of today, November 26, it doesn't hurt walking or just sitting there like it did for a few days after the ride; it just hurts when I try to ride or start to becoming active. On a pain scale 1 to 10 the first few days was maybe a 7 now its down to I'd say a 3.5 to 4 but only when I'm active. I have been fitted to the bike for the most part, I understand the more I ride the more smaller tweeks will be made. I was just wondering what could possible be the problem. Thank you.
