With the internet the ability to quickly find something out is only a short tap away.
Type “running enter what you will here” and you will have more results than you know what to do with. So it is key to try and find the most relevant parts to the search results for you, this can be hard and can end up trawling the results for some hours without too much, again everyone is different so reading as much as you can always helps.
I have found that YouTube has been very good in not only reviews but also techniques to be used when running, warming up or down and eating.
One of the better ones I have been viewing is the Running Wild by 2 people who seem to be able to convey things very well for a newbie like me anyway.
One for reviews who is very good and has a good following is DC Rainmaker who does some excellent reviews of equipment he uses, allowing you to compare different makes/models and also allows other to comment on their experiences.
Lastly for reviews on running shoes etc it has to be Running Shoe Guru who has a nice site which allows you to find the correct shoes based on experience of a user.
Go and give them a look, I am not affiliated with them just find that they really do help a newbie.
