Hope I can get some insight here. I started running about four months ago and absolutely became addicted! So much so that I increased my mileage too quickly (5 miles was my maximum, usually alternate between 2 miles and 4 miles daily, 6-7 days per week) and have injured myself. First I had tendonitis in my right foot. I recovered, started running again - 23 miles the first week back (loved it!) - then the shin splints hit my left leg. REALLY painful! I have an elastic ace bandage on the ankle and am taking Advil religiously. Yesterday my stationary recumbent bicycle was delivered, so I am going to cross train with it - instead of trying to run every day (when I get healthy, that is). My plan is to alternate daily between the bike and the treadmill, and run no more than 4 miles on the treadmill - seems like when I go further than that I get hurt! Both the treadmill and the bicycle are gym quality (could have had a couple additional Chanel handbags for what these set me back!) so I don't believe the treadmill is the cause of my injuries. Anybody have any similar experiences and or health/training tips to share? TIA! PS I should add that I am not overweight (could lose 5 pounds, though!) and am 40+. Haven't worked out much over the last few years but have always walked 3-4 days per week. Former avid tennis player (in my before kids days!).
