15' warm up - nice smooth spinning - then shift into a the big chain ring and into a gear that allows you to spin at about 65-70 RPMs. You will spin 4x10 minutes in this gear - HR should be mid-high Z2 - recovery will be 5' easy between sets - you will probably see HR drift into Z3 - keep the cadence up - this is where you build strength. 10' cool down.
Run BEFORE Bike BRICK
Run on a flat course or treadmill. Keep HR in Zone 1-2. Think about form and running pretty. Stretch when done and add in Core 1, 2 or 3.
