Today’s zone 2 runs was mentally difficult because it’s so easy for my ego to kick in and run quicker than I’m supposed to. To reach a goal it’s incredibly important to put ego aside and stay disciplined. Zone 2 training increases mitochondrial density as well as MCT-1 transporters. By training Zone 2, we will not only improve fat utilization and preserve glycogen, but we will also increase lactate clearance capacity, which is key for athletic performance. An endurance athlete should never stop training in Zone 2. The ideal training plan should include 3-4 days a week of Zone 2 training in the first 2-3 months of pre-season training, followed by 2-3 days a week as the season gets closer and two days of maintenance once the season is in full-blown. #zone2 #runningtips #ultramarathon #fitness #fitnesstips #strava
