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.
ONCE YOU ENTER YOU WILL RECEIVE A CONFIRMATION EMAIL. MORE INFORMATION ABOUT YOUR RACE NUMBER WILL BE SENT CLOSER TO THE EVENT – ENJOY!
