Each kilometre is accurately marked with distance flags and our friendly marshals will guide and cheer you all the way to the finish. We cannot wait to welcome you to the London Half Marathon & 10k Presented by TREK.

With RunThrough you can expect a friendly team of marshals to help guide you round the course and cheer you on to the finish, a lively and well-serviced event village with plenty of food and drink options including free goodies from our partners at the finish line after your hard effort.

We have been extensively researching what runners consider important, and sustainability is fast becoming the top issue. Click here to see what RunThrough is doing for sustainability.

You can now grab your London Half & 10k Presented by TREK event t-shirt for more than 30% off when you buy it as part of your entry on checkout! With the event logo printed on the chest, it’s the perfect keepsake to celebrate your race and wear your achievement with pride!

We can do this with our partner RT Kit as part of a strategic decision to raise awareness about the quality of the product whilst reducing the overall cost of events for those who would prefer not to have a t-shirt included.

Come and enjoy the day with us. Once you enter you will receive a confirmation email. More information will be sent closer to the event.

We can’t wait to see you on the start line!
