I'm a new runner doing c25k. I've been doing 3 weeks with no problems until now. I did walk alot previously, but never jogged. I went to a running store and got nike free run 3.0's. I was previously wearing vibrams. Since they were new shoes, they wanted me to use a treadmill in case I needed to return them. Shoes feel great, no blisters. I'm having bad leg pain though, that has caused me to not be able to run. I ran through it one day and it got worse. It starts in the middle lower knee and goes to the side of my inner leg just below the knee. It's more in my leg then my knee. Anyone know what that sounds like? I have never ran on a treadmill before. So, the two things that changed were my shoes and running on the treadmill. Any idea if it could be either of the two and which one possibly? I miss running and want to keep going, but not sure if I should still do it since the pain is still there. I do feel it in the same place on both legs, but the left is alot worse then the right.
It could be an alignment/balance issue, so you may want to consider inserts or even a different model of shoes. It is a good idea to get a professional opinion, but a lot experts also recommend stretching/strength exercises for the hamstrings and quads.
Just take things slow and check it now so that you can correct the issue and continue with your progress.
Wishing you all the best
I'm wondering why you moved away from the Vibrams. The change in shoes combined with running on the treadmill may have encouraged you to change your form You may be lengthening your stride and extending your feet further in front of you, putting more strain on your knees and lower legs. Check your form and footplant, maybe go back to the Vibrams to see if there is any difference.
I think it's both shoes and treadmill.
First, the treadmill. People almost always set them on an incline, which strains the plantarflexors that anchor on the lower leg and can cause pain below the knee. In the real world, we are not always running uphill. We shouldn't be doing that on treadmills, either.
Regarding shoes, I would never recommend that a tenderfoot runner jump cold-turkey into a running program with either Vibram 5-fingers or Nike Frees. There simply isn't enough structure in the shoe to shore up muscles, ligaments, bones and tendons that are not yet conditioned to go it alone. Start with a more structured, unnatural shoe to match the unnatural rigors of running and the artificial surfaces we run on. As you build up your muscles, you can gradually wean yourself off the support gear.
When I bought the first run of Frees, instructions in the box said they were for intermittent use for just a few miles at a time until you build up for the lack of structure. They specifically said not to use them as a regular trainer. I experienced pain when I ignored their advice and tried, too.
Like all strengthening exercises, unstructured footwear can be overdone to the point of weakening you. However, they have value in gradually building up to a regular program as the Free instructions originally advised. The idea is to prepare, then execute. If you try to do both at once, you are likely to experience setbacks like these.
