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.
T-Shirts at events have become a hot topic with concerns around the quality not being high enough to wear on a regular basis. 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 Darwen events logo printed on the chest.
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.
