Starting with just under 1,500 runners in 2003, the Cardiff Half Marathon has been continually growing in size with 19,200 runners crossing the finish line last year.
As well as the thousands of charity runners taking part, there will be a number of serious athletes running to cross the finish line first.
Runners will be looking for cool, dry conditions with a light breeze to make for the best conditions to complete the Cardiff Half Marathon.
