Question for the experts about substituting long/slow rides for shorter sweet spot rides (per this bit): I’ve got a long event (not a race, 150mi charity ride) planned, so I’ve been doing the long/slow alternate workouts on weekends during SSBMV2. I’ve got build (GBMV) starting in a couple weeks. Should I keep doing the long/slow alternate instead of shorter sweet spot, or was that recommendation really just for base phases?
