Ifrider, go on to runnersforum, its a great site and everybody is extremely friendly. As oposed to a mountain biking forum where some people run, you get a great section of runners from people just starting out like yourself to ultramarathon runners and all in between.
Ref gait analysis, im 35 and have been involved in a lot of sports over the years. I always believed it was a load of old rubbish and designed to get a lot of cash out of niave runners. That was until about a year ago when i started to get a recurring injury in my left calf muscle. After a lot of rest then running again it happened again so i saw a physio.
Long story short is for some reason my left calf was building a lot of tension due to my running style and i was advised to get analysed.
So far so good. 3 months on and running regularly with no problems. (fingers crossed)
But to be honest at your stage i doubt very much you need to do this.
But honestly try runnersforum. Its a cracking friendly forum. And good luck as running is fun once your body adapts 😀
