However, Fairbridge, which helps young people in South East Wales find education or employment, hopes to get more people fired up.
Registration for the event, which includes two hours of training, starts at 6.15pm with the walk beginning at 8.45pm.
A minimum pounds 100 donation is needed to take part and all firewalkers will be given a buffet and certificate of achievement.
