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 Windsor Trail Run 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!
