Ben Greenfield gets his lactate threshold tested at Meadowlands Stadium in 3-minute stages up to 193 bpm. His threshold sits around 178-179 bpm, where lactate hits 4 mmol, meaning he can sustain just over 9.5 mph without crossing into anaerobic territory.

Questions this video answers

70% of Ben's heart rate.

193 bpm.

Between stage 5 and stage 6.

Between 178 and 179 bpm (approx).

About 182 bpm when lactate was around 4 mmol.

Hey, it's Ben Greenfield here, lying on the post workout table as the doctor removes my cannula. And I just finished a lactate threshold test run by the Corey Stringer Institute here at the Meadowland Stadium where I'm attending Team timexcam. You want to go over what we actually saw in that data?
Sure. So what we were doing is we were increasing your stages, 3 minute stages, and your intensity started at 70% of your heart rate. And then we went right up until you were pretty maxed out at 193. Three was where we got your heart rate here. And it looks like your threshold was somewhere between in stage five and six. It was somewhere between a heart rate of 179 and a heart rate of 178. So looks to me like your lactate was right around when it was reaching 4 millimoles. You were about 182, heart rate, and your speed was just over 9.5 miles an hour.
Nice. So now I know exactly how hard I can push without going above that threshold and burn in too many matches. So there you go. It's good data.
