Mia Farrow was introduced to the HRST in December 2021, shortly after she shared her big endurance goal of running Aconcagua360* with her then strength coach Peter Kirk.
*Aconcagua360/Project Argentina is a 110km FKT speed hike/run from the bottom of Aconcagua to the summit and back down the other side of the mountain, connecting the 2 gates. Start is at 2,800m, summit at 7,000m, and finishing at 2,500m. Current WR for women Solo is at 47 hours nonstop.
The thing she truly appreciated with the HRST is the minimalistic approach, it wasn’t taxing on the body, and it still engaged her in the movement of proper mechanics, proper breathing, and balance and coordination—which she needed for trail running and mountaineering. This was also good way to add more endurance work without stressing the legs especially after an injury. Besides, they were in the middle of an extremely hot summer in Sydney Australia—so doing the HRST in the shade vs running for hours in the hot sun was a smarter way to train.
Mia’s first HRST assessment was at 4min intervals and it took a few sessions for her nervous system to adjust.
Mia remembered it required focus and patience, being able to relax and breath (inhaling on the 2 steps-up and exhaling on the 2 steps-down) while alternating feet, and it probably took 6-8 weeks to comfortably move through different set-ups based on tempo/pace.
She has equally started enjoying 19 and 24 SPM, her coordination was better and so was her HR recovery.
After 12 weeks, she decided to speed hike / run one of her favourite peaks in Oz, twice in the same day, 3207m elevation gain, some 33km RT. (21 miles 10,521 ft elevation gain.) And it was a success.
With Mia’s words:
“Needless to say, the 3 weeks expedition in Argentina was a huge success and carrying a 20kg pack at such high altitude was comfortable.
I look forward to testing it out at a 50km UTMB race next week and climbing & speed running Mt Aspiring in New Zealand in February.
My resting HR this year has come down to 39-40, from some 47-48 a couple of years ago. Given I’m well into my mid 40’s, it’s a good feeling, to be getting fitter and stronger.”
