Lars shares how a Minnesota ski racer turned runner fits two runs a day around a full teaching job, from a 5:30 am shake out to afternoon sessions after school. He explains how his Nordic background shapes his training, why he keeps easy days really easy, and how he ramped up to 135+ mile weeks. We also get an honest look at Berlin as part of Puma Project 3, where he set a PB by 18 seconds but had to let go of his sub 2:10 goal mid race, plus a deep dive into his double threshold sessions and strength routine.
