RT Races

Would you like to take the distance you are running to the next level? Go from 10k to Half Marathon to Marathon to Ultra Marathon? Then we have to race for you!

The course is a 10km loop and you decide on the day if you want to run 10km, Half Marathon, Full Marathon or an Ultra Marathon. If on the day you only want to run 10km then you can stop and still be in with a chance to win the 10km race!
If you want to carry on then you have the option to complete the Half, Full or Ultra Marathon distance and maybe win one of those races or just see if you can complete an Ultra Marathon for the first time?

Because it's a loop you will be able to have a large drop bag so you will be able to try different shoes, backpack, nutrition and have anything in your drop bag to help or try out!

Enter three races and the third is free!
