I have been running for about a year now and have never really subscribed to the idea of warm ups or cool down stretches.
Most of the time I will start a run with a brisk walk.
Some of the time (but rarely) I will finish a run with a brisk walk
For the better part of this, I haven't suffered any problems.
At the weekend I ran my first Half Marathon and was extremely pleased with the results. The only problem was that at around 10 miles I could feel the top of my thighs starting to ache. Despite this, I pushed on to the finish.
Following this, I have been suffering. My thighs have spent the best part of 3 days burning and causing me difficulty moving. Even today, I can still slightly feel the pain - although it isn't causing me any issues now.
Based on this, I gathered that this may have been reduced or possibly eliminated if I had done some post run stretching.
So, while I am aware that I may need to do some stretching, I have no idea how to. Are there any guides on what and how I should be doing these post run stretches? It is all well and good sites saying stretch this muscle, stretch that one, but some video tutorials would be nice 
Any help would be appreciated.
Thank you,
