Prepare to run, jump, climb and crawl: the Bermuda Triple Challenge is back, and registration is now open.

Challenges range from scaling a Bermuda bus to the Royal Bermuda Regiment’s assault course and a zip line.

Organisers of the event have reported “strong” initial registrations, and not just from residents: the obstacle course challenge has caught on among visitors as well.

The three-course, three-day event has raised more than $250,000 over six years for youth-based local charities.

Jason Correia, a co-director of the challenge, said that obstacle course racing was “booming” around the world, and conditions were good for evolving Bermuda’s races into a global tourism event.

“We are expecting close to 50 international visitors this year, thanks to the support from our sponsors Argus, Chubb, Sun Life Financial International and the Bermuda Tourism Authority.”

This year’s supporting charities are Scars, Knowledge Quest, The Reading Clinic, Raleigh, WindReach and the Somerset Primary PTA.

The Bermuda Triple Challenge’s scoring system combines finishing times and charitable funds raised to encourage participants to raise funds on behalf of the charities.

Reid Robinson, its co-director, said that winning “does not mean you are the fastest or the strongest, but can complete the fun and challenging obstacle courses, as well as raise funds on behalf of our great charities”.

The challenge is open to individuals as well as teams of two, three or four.

All obstacles are optional and participants can opt for an alternative exercise instead. The team with the most Challenge and Charity points wins the $1,000 grand prize, with $5,000 of prizes also available.

The Bermuda Triple Challenge kicks off at 7pm on Friday, March 17 with the Argus Urban Foot Race through St George’s followed by a community block-party with DJ and a bouncy castle. The Royal Bermuda Regiment hosts the Sun Life International Island Challenge on Saturday morning, followed by a post-event barbecue hosted by the Royal Bermuda Regiment and Butterfield & Vallis. Sunday’s closing will see participants in an all-out assault on the Royal Naval Dockyard in The Chubb Royal Challenge, followed by the Buzz/Butterfield & Vallis participant appreciation brunch.
