An Ironman 70.3 race is among the toughest challenges (you may actually do)
The folks at Livestrong.com asked me to make a list of the “toughest endurance challenges (you can actually do).” So no double Ironman races, 100-mile runs, or marathon swims.
I doubt if anyone has done all 10 since you’d have to be into distance running, adventure racing, triathlon, stand-up paddleboarding, and open-water swimming. Plus several of the events only have been around for several years. But I’m guessing someone will knock out all ten at some point.
If you live in Florida, you’re in good position to tackle the list since 6 of the 10 events come to the Sunshine State.
Here’s the LIST. How many have you done?

Two of those events were in Pasco. Unfortunately, were in Pasco.
