Support Diabetes UK by applying to run in the Great South Run on Sunday 22 October in Portsmouth.
The 10-mile event is the UK's fastest-growing running event and places are now only available through charities and running groups.
"We have already been overwhelmed with calls from people wanting to take part, but we still have places left to fill" said Penny January, Diabetes UK fundraiser for the South East.
"Diabetes is a serious condition which can lead to serious health complications. It is vital that we continue to raise more money to fund research and projects into finding a cure for the condition. This is a great event for runners to test their abilities."
Diabetes UK will be organising a post-run hospitality event including refreshments and masseurs.
