London Track House

Tracksmith's training series leading up to the 2025 London Marathon

About

Every year when days are darkest, marathoners pull out their calendars and circle a race date in the spring – making a commitment that they know will take time, hard work, and consistency. That’s why every winter, Tracksmith kicks off our 100 Days long run training. It’s a celebration of the commencement of a marathon build, but also a resource for runners to share the work, celebrate the journey, and prepare for race day. We focus on the key element of marathon training – the long run. And we do our best to bring you everything that you need to be successful while you’re putting in the work – so that you can do everything you need to do to be successful on race day.

The countdown is on. Get ready and share in the process with us this year. If you’re interested in sharing your marathon journey with us by joining us for some runs and activities, you can sign-up to stay up to date.

Join us in London as we get ready for race day with a long run training.
