Notice that for Athlete 1, blood lactate remains steady at their estimated anaerobic threshold (12km/h) and lactate begins to accumulate when the pace is increased to 13km/h in the final 15 minutes. For athlete 1, this is confirmation that their anaerobic threshold pace is reasonably accurate. For Athlete 2, lactate begins to accumulate during the middle 15minute segment (their estimated threshold) and continues to do so during the final 15 minutes.

Thanks to a field of star-level golfers and some of the most prestigious courses in the country, the Open continues to be the center of the golf world whenever it gets underway. Fitting right into the equation is Erin Hills Golf Course in Hartford, Wisconsin, the site of the 2017 U.S. Open. Erin Hills has never held the U.S. Open, although it has held the U.S. Amateurs, the U.S. Women's Amateur Public Links and other tournaments as well.
