How to improve your half marathon time
Improving for a good half marathon time takes effort and dedication. But with the right plans in place, you can achieve the consistency you need to make it happen and push your PBs. It means going faster and further as you train, and the best way to achieve that is with a workable structure, so:
Follow a half marathon training plan
A training plan gives you a visible structure and route to your half marathon. Ticking off the days is a great form of motivation, and having a calendar to work with enables you to plan ahead and organise your days around your runs.
Work on your running pace
Gradual improvements and mini goals during training can help you to improve your pace and run towards a faster finish time. Knowing how to run faster will help you to implement speed play into your training, along with tempo runs and intervals.
Go harder for longer
You should look to work on your stamina as well as your speed. Knowing how to run for longer without stopping or getting tired is key when it comes to training for longer distance runs, as it can be just as much about training your mind to focus and keep going as it is about training your body. Strength training can also be of benefit here, as it helps you to run more efficiently and can help to prevent injuries too.
Get the right footwear
Finally, be sure to take good care of those all-important feet that will be carrying you through the 13.1 miles to the finish line. Investing in a pair of the best half marathon shoes will work wonders for your endurance and make training much more enjoyable and effective in the process.
