£5,250 prize purse for the top 5 male and top 5 female runners


The South Downs 100k entries are now open.

Covid-19 Cancellation Policy:

The South Downs 100K will be organised to go ahead with Covid-19 measures in place as specified by UK Athletics. Hopefully, by May 2021 these measures will no longer be necessary, however there is a chance that Covid-19 may still be a factor. For this reason, we have decided on the following policy: If the event is cancelled or postponed due to Covid-19, runners will be able to cancel their place and receive a refund of 70%. Alternatively, runners can defer their place, free of charge, to either a postponed date later in 2021 or to the following year's event in 2022 if the race is cancelled.
