The Sub-32 Marathon Club (also Sub-3 Squared Club) is a select group of endurance athletes who have swum a full 10 km marathon swim without a wetsuit, fins or paddles under 3 hours and who have also run a full 42 km marathon run under 3 hours.
The 10 km marathon swim can be done in fresh or salt water, but must be correctly measured by GPS and not done downstream in a flowing river. The marathon swim can be done solo or as part of a race. The marathon run can be done in any marathon running event or a solo run documented with GPS by an independent observer.
After posting this challenge in the triathlon community, many endurance athletes claimed that many triathletes can do both sub-3 running and swimming marathons over the course of their career and most professional triathletes can do so back-to-back.
While that Sub-3² dual feat may be the case, it has yet to be documented in a competitive setting.
Miller explains his challenge here. “I issue this challenge to the professional triathlon community because a charity race between two endurance athletes, mono-a-mono, would be an amazing way to not only push ourselves to the breaking point, but most importantly, create a media buzz by doing it in the name of charity! I picked the triathlon community out of respect, as I have seen first-hand the grueling training involved in preparation for an Ironman race. Personally, I want to see what some of their finest can bring to the table.”
“The difficulty of the Sub-3² Challenge is vastly under appreciated by top endurance athletes. Swimmers can easily do a sub-3 swim marathon. Good runners can easily do a sub-3 marathon run. But a back-to-back run-swim at a sub-3 marathon pace is more difficult than meets the eye,” explains Steven Munatones who came up with the concept. “Therefore, I sincerely hope that top triathletes will be willing to race against Darren to prove that the Sub-3² Challenge is a doable achievement. The race will be something that I greatly look forward to watching.”
Miller outlines the invitation, “I am flexible with an early/mid-summer date off the coast of southern California. At this point, I am pushing for Memorial Day weekend [around May 25th]. A 26.2-mile marathon running course will be GPS mapped by veteran marathon and ultra-marathon runners, beginning in the Oceanside/Carlsbad region, and running south toward La Jolla Cove. The 6.2-mile swim course will be a last minute decision, as I have local marathon swimmers keeping an eye on the tides. It could be a direct shot down the coast, or follow and ‘out-and-back’ pattern from the starting location. My challenger will be provided with everything they need, but is more than welcome to bring their own support vehicles and crew; both on land and water.”
Perhaps wearing Nike gear, they will Just Do It.
