Grand Canal Challenge Volunteer If walking or cycling 26 miles sounds a bit daunting, why not offer to volunteer at our Grand Canal Challenge on June 25? We will need people to cheer on our team as they make their way along the Grand Union Canal – the perfect opportunity to soak up some summer rays while feeling great about doing something for charity! If you think you could spare a few hours helping out with cheering, giving out refreshments or congratulating our team as they cross the finish line, we’d love to hear from you! Email us at email@example.com or call us on 020 7351 8613. Thank you.
