The Nuffield Health Challenge kicks-off at half-time in Saturday's game at home to Gillingham.
From now until the end of the season, the half-time break will feature a supporter having three attempts to hit the bar from the edge of the 'D'.
Anyone who succeeds in hitting the bar will win a 12-month membership at Nuffield Health, Fitness and Wellbeing at Alma Leisure Park in Chesterfield, worth £450! This will allow them to use all the facilities there, including 20m swimming pool, spa pool, steam room, sauna and fully equipped fitness area.
Those who fail to meet the challenge will be presented with a seven-day pass, again allowing use of all the facilities.
Christian Perrin will be the first supporter to face the Nuffield Health Challenge.
Supporters will be given an opportunity to take part in the challenge at half-time in future games so don't forget to follow the club's Twitter feed and 'like' the Facebook page.
