ESPN takes a look at the Great World Race which has a $60,000 entry fee (7 marathons in 7 days on 7 continents)

Ryan Hall completed this in 2017.

Most of these people will be jogging to complete the distance. I think what Jordan Tropf did in 2021 was more impressive:

Saturday, Oct 9 - Baltimore 2:27:23 (2nd overall)

Sunday, Oct 10 - Chicago 2:31:54 (63rd)

Monday, Oct 11 - Boston 2:32:13 (110th)

So did Jenny Simpson. She ran them all around 3:15-3:30 until the last one where she had to walk.

The North American ‘Thon Trifecta will be more affordable and won’t be televised.

I know a couple people that have done it, I know a lot more people that could do it but Money. There's a Marathon series called Mainly Marathons, a lot of people are doing 7 in 7 days or more all the time. Post #3 mentions most will be jogging it. So what? First, that triple performance is amazing. Second, I give credit to anyone who does 7 in 7 days even it's with Mainly which are basically out n back loops. I'm a very experienced Marathon/Ultra runner, 100+. I have run two in two days (Marathons and Ultras) several times, I don't think I could do 7 in 7.

Last year I met a guy who had done this.

Running 7 marathons in 7 days is not that difficult. Paying $60,000 and polluting the planed with endless flights is a whole other story.
For $60,000 you can easily travel the world for a year and have money over.

My thoughts are it's a giant carbon spewing racket. But in that way it's really not all that different from the World Marathon Majors. I'm just surprised the influencers like Kofuzi, Believe in the Run and the British Bens haven't done it yet.

A marathon is a race. Are these races or are they fun runs?

That looks like a Dahl Marathon series ... it doesn't exist. There is nothing even remotely impressive about that even if it was real.

What rojo reported is an actual 7 day marathon series, with travel, sleep and other logistics weighing heavy in the equation.

Sorry, malmo, but it is true. I failed to mention that he did this while doing his surgical residency.

A Sprint of Marathons: Jordan Tropf Knocked Off Baltimore, Chicago and Boston on Consecutive Days in the Prototype of a New Under Armour Shoe

As he crossed the finish line of the Boston Marathon against a backdrop of raucous cheers and clanging cowbells, endurance runner Jordan Tropf finally had a chance to catch his breath after a whirlwind journey that included f...

To me, it is not terribly impressive. True, most people couldn’t do it. But those that could wouldn’t want to. Why drive your body to a point of brokenness so that you can barely run or walk? I don’t think it’s the mark of a great athlete.
