Places are already available to run the Cardiff Half Marathon in October this year.
Charity Diabetes UK Cymru wants to build on the 50 runners who raised £3,500 by taking part last year.
National Director of the charity, Dai Williams, said: “Signing up to run the Cardiff Half Marathon now is the perfect way to stick to your New Year’s resolution to get fit and raise money for Diabetes UK Cymru.
“More than 153,000 people – almost one in 20 – are now diagnosed with diabetes in Wales and that number is rising rapidly every year.
“Money raised by our Cardiff Half Marathon runners will fund vital research into the condition and help us provide advice, support and information for people with diabetes in Wales.”
