XC skiing 48:22 [3] 4.62 mi (10:28 / mi) +125m 9:39 / mi
Skied around Trillium lake with S on my back, classic skiing after Mountain Edition Stars & Guitars!
Breathing approach: took 2 puffs albuterol before heading out, kept mouth covered with buff, breathed through nose as much as possible, took it relatively easy
