So, I took the two best NCS nordic racers for an out time workout. We ran an easy one mile warmup, and then four 100 meter intervals with stretching and 300 meter jogs in between. After that Hyelom and my daughter Lucy did 20 minutes of double poling, while I continued to do laps on the track. (It was Hyelom's first day on roller skies and he looked pretty good.)
