Training or more specifically speed training, to some it’s a bit of a dirty word. Something for serious runners that people may not be sure they like or want to be like. And once you can already run what ever distance you want comfortably why train more and that is valid. Being able to run means you’ve worked hard and your fitness is already miles better than most of the population.
There’s a couple of reasons to consider it.
It’s one of the most social forms of running as if the session is well thought out it’s very easy for all abilities to come together and do the same session. They tend to have plenty of recovery periods which is great for chatting while you get your breath back. This is especially true for hill sprint training. Sprint up (at your pace) and walk up
It can help you improve, many runners would like to be a bit faster and there’s nothing wrong with that. Hill training can also help make you stronger which in turn can help you stay injury free.
Variety, it’s another type of running activity and mixing up what you do can help keep things interesting. The social side can also help when motivation is low as while you may not be quite in a running mood you do get to see friends and that is good!
