Hoping maybe one of you more experienced runners could weigh in on this:
I started running (every day) and got up to about 5K a day. Nothing stellar in terms of speed, about 20 minuets for the whole run.
over Christmas I was relegated to a treadmill which I found to be stupidly easy. As a result I bumped up the runs to 10K in about 45 minutes. The run felt fine but soon after I started getting sharp pains down the sides of the kneecap in one leg. I assumed it was because I'd pushed too hard, so held off for a few days. Tried again after 5 days off, and after about 10 steps the pain was back, strong enough to cause me to sit down.
Again, I gave it 5 days and tried a cross-trainer. This time no pain at all, so after 24 hours off, I try running again. Mistake.
Its been 20 days since I last ran, and while the day-to-day pain is gone, even the slightest hint of jogging up stairs brings it back with a vengeance. I've got an appointment booked with a sports doctor to discus, but wanted any tips on low-impact cardio.
Its taken me 20 years to get to the point where I was exercising daily, I really don't want to go back to being a fatty because I fucked my knee.
