Events Supporter events Redbrik Chesterfield Half Marathon Support us by taking on 13.1 miles around the streets of Chesterfield. 2000 runners are expected to turn up for the Redbrik Chesterfield Half Marathon, taking place on Sunday 18th October 2020. If you don't fancy taking on the full half marathon, there will also be a five mile run and family fun run. We are proud to be charity partners of this event again. With a portion of your entry fee coming straight to us, taking part in this event means we can offer more help to children and families who need it. Half marathon early bird entry is £23 until February 29th, when it will increase to £29. Please visit the Rebrik Chesterfield Half Marathon website for more information.
