5k is one of my favourite distances. I’ve spoken a lot about 5k races on my blog, mainly Parkun! Running a 5k should not be underestimated, especially if you want to run it in 25 minutes or less. There’s a decent amount of training that needs to go into your training plan in order to get you where you want to be. When I first started running all those years ago, 5k was a distance that I enjoyed building up to.
