Tip 3/50. ***X I’m very tempted to say get a new pair of race shoes if you only have regular trainers. These should make a noticeable difference. The downside is that you will not necessarily have had chance to get used to them. Then again you are only running 5k and not a marathon.
All the suggestions are starred:
*** 3 stars. IMHO it will work
** 2 stars. It might work
* 1 star. Can’t hurt
X 1 cross. It CAN hurt if done wrong.
All 50 tips are shown here as a series of posts : https://the5krunner.com/tag/how-to-get-a-5k-pb/ or on twitter using #howtogeta5kpb. They are all SHORT-TERM tips that will work in the next week or so with varying degrees of success.
