    an average of 54 miles each day

    It also mention she ran 17 jours a day. I can’t imagine the kind of energy it takes to keep that pace going for 40 days. Absolutely insane.

      That’s like 3mph for 17 hours. Jesus…. That’s a lot of wheaties… by my back of the napkin calculations that’s burning like 4200 calories a day.

        I’m not sure two marathons per day can be qualified of lower intensity.

          Of course it can. You just need to define what you’re comparing it against. Surely two marathons per day is lower intensity than two marathons per half-day or 3 marathons per day.

          The amount of work done and intensity (the rate at which work is done) are two different measurements.

          Both of you are kind of right. It’s still an insane feat of endurance but averaging an 18 minute mile is pretty damn slow and likely zone 2-3 even in rugged terrain for an athlete like her.

          High intensity isn’t just a generalized term but specific to heart rate, lactate buildup, and anaerobic states.
