First and foremost I think it’s important to celebrate what a strong runner you are. That’s evident in some of your race performances in recent years and something to take confidence from. Now it’s just a case of taking that talent and potential, training smart and seeing where it can take you.
We also want to try and make sure there is plenty of variety in the training to keep it interesting, but always working towards becoming more competitive and stronger over the longer distances.
Strength and flexibility are the two areas you highlighted as your weaknesses. Possibly the least enjoyable part of training. But it’s finding what motivates you to complete them and finding some routine in your week where you can repeat them on a regular basis.
It’s especially important as you increase the distance to make sure you are strong as there are lots of ultra runners picking up some serious injuries.
