Hey folks, I have been mountain biking for a few months now, was really building up my strength and just have a blast riding 3 - 4 times a week. However, about 2 weeks ago I came to realise that sometimes I may be a bit too busy to ride, so thought that I would start running in between the days when I am riding. Saturday was my off day. One morning I went for a 8km run but at a high tempo/quick pace. When I got home felt a very light pain in my left knee. That same day I went for a 40km ride. Next day my knee was feeling sore. Took a day off, then this past Sunday went out for a ride, however this time my knee was really painful so cut the ride short and went home. Since then I haven't done any exercise, this morning I thought I'd go for a very light and short run (just had to get out). To sum up the run, it was rubbish, reason being I ran for about 2km, and my knee started feeling 'tight' and sore, so called it a day. The pain is on the inside of my left knee, and it hurts when I lift my knee up and down, otherwise I can walk just fine. What am I doing wrong? Should I be resting more? Rubbing something onto the knee? Ice?? Any constructive advise would be greatly appreciated. Really upset at the moment because I started feeling good and fit, and as much as I want to be training, I just cannot because of this pain in my knee.
