Marathons, Ultras and now Half Marathons!

10 in 10

2022 will see our 8th 10 in 10 Event

One of the original UK events of this type, we started life as The Great Barrow Challenge and retain this name for our 10 day summer event.   We are located in Barrow, Suffolk and this is most definitely a challenge!

We use a variety of routes throughout the event.  Some single loops others are multi lap. 

All start and finish in the same place and take you through the lovely Suffolk countryside.

New for '22 will be a Thai/fusion restaurant/ bar on site 

On the edge of a village you will find 2 convenience stores and a pub all within walking distance

If you are travelling by public transport and cannot carry a tent or bedding etc. please get in touch with us and we will try to help from here. 

We have one luxury pod available, again heavily discounted for the 10 day event and would be suitable for 2 runners to share. 


In the event of a frustrating cancellation due to Covid your entries will roll over to next year or be available to use on individual race days.
