One Hour Workout: 3×12 Trainer Intervals

Push through the mental and physical barrier of settling in at tempo effort in this one-hour trainer workout from coach Mike Ricci.

This week’s bike workout comes from Boulder, Colo.-based D3 Multisport owner and head coach Mike Ricci. Similar to his recent bike workout, the intention of this trainer session is to transition from tempo pace to lactate threshold (or Zone 3 to Zone 4) and push through the mental/physical barrier of settling in at tempo effort.
Note: IF is “Intensity Factor” or the percentage of threshold power
