Along with fleeting daydreams of snow-covered fields, the summertime for many nordic skiers and coaches brings the search for another surface: perfect pavement. After living in Bozeman, Mont., for the past two months working as the new head coach for the Bridger Ski Foundation (BSF) elite program, Austin Caldwell deemed the newly paved roads running past Triple Tree Ranch his rollerski route of choice.
The best part about the route for Caldwell, however, is not just that his athletes do not have to dodge potholes or endure the consequential leg gyrations from rollerski wheels passing over pebbles. It’s also the interval loop the location provides.
Performing interval pieces on the same loop, to Caldwell, offers athletes an opportunity to track their improvements not only through one workout, but over the course of many. Caldwell’s workout of choice is done at threshold on the same loop so that athletes can track improvements as the workout progresses.

Caldwell says that the athletes should then return to the same location and perform the same workout a grand total of four times in the summer and twice in the fall. In order to track performance gains, Caldwell has his athletes calculate their average heart rate during each interval piece, along with the amount of time it took to complete.
“The main thing that I like about this workout is that people can look back at it over time and see improvements,” Caldwell explained on the phone. “We look at the average heart rate and look at the times down for each interval and it’s a workout we’ll come back to a few times throughout the summer and a couple times in the fall as well, so you can see improvements throughout the year and I think that that is very motivating in the long run.”
