Those who are successful and hit the cross bar will win a signed shirt and the first entrant to hit the cross bar will also win a cash prize of £500!
The Cross Bar challenge is sponsored by Mitsubishi and takes place during half time at each Gloucester Rugby home match.
Those who take part in the challenge will be invited back to the last game of the season for a chance to win the Mitsubishi ASX 2.
Tickets to take part are sold at the stadium ahead of the game and are just £1 per ticket.
