Walk, jog, run or ride along the Grand Union Canal, joining our two hospitals in one fantastic summer event on Sunday 25 June 

What does it involve?

After a truly spectacular event last year, the Grand Canal Challenge is back again in 2017 and it's even bigger and better than before. Join us on 25 June for routes along the Grand Union Canal and a Finishers' Festival at Harefield Hospital.

If you're feeling energetic, why not go for the full 26 mile route? If that sounds a little daunting, never fear... There are also 12 mile and 6 mile routes. Whatever your ability, we'd love you to join us.

It's not a race, so you can go at your own pace and enjoy the painted canal boats, lush green scenery and checkpoint refreshments as you pass through West London, out into the gorgeous countryside. 

And once you've reached Harefield Hospital, you'll be welcomed by our Finishers' Festival. There'll be music, food and drink to help you celebrate your fantastic achievement!

Where will my money go?

Your money will go towards supporting the health and welfare of patients by providing state-of-the-art equipment and new facilities, as well as supporting cutting-edge research into heart and lung conditions.

How much does it cost to take part?

Registration costs just £15 each. 

We ask participants to raise a minimum of £150 in sponsorship to support the work of the hospitals. 

Anything else I need to know?

We need volunteers to help with marshalling, cheering on our participants and to carry out general tasks on the day. If you'd like to volunteer to help us make the day as successful as possible, we'd love to hear from you. Simply book your volunteer place using the booking form below - you'll receive a free T-Shirt and refreshments throughout the day.

Dogs are welcome on the day, provided they are kept on a lead at all times and that owners adhere to the Canal & River Trust's guidance

You should also probably know that we had a bloomin' marvellous time at last year's Challenge and we expect this year's to be even better. In fact, it was so good, that the lovely people over at Hitachi made a video of the day. Check it out below.
