If you would like to amend your estimated running time please contact us here, clearly stating your full name, postcode, which event you have entered and your new estimated running time. We will then be able to amend this for you. 

This is an important safety measure and we ask that you enter an accurate time.


Please ensure you notify us at least 6 weeks prior to the event (10 weeks if you have entered the Great North Run) otherwise we will be unable to amend. Please see the ‘Zone Start/Wave Allocation’ section for more details’.
