We have been extensively researching into what runners consider important, and sustainability is fast becoming the most important area. Click HERE to see what RunThrough is doing for sustainability.

T-Shirts at events have been a hot topic mainly around them not being a high enough quality to wear on a regular basis. So we have decided to tackle this by offering a RunThrough Kit Technical T-Shirt with a retail value of £22 for £12  with the addition of the event logo printed on the chest.

We can do this with our partner RT Kit as part of a strategic decision to not only raise awareness about the quality of the product but also to counteract the increasing costs incurred in event production in the current climate.
