Race Rehearsal
55 min · 49-59 TSS · IF 0.76 · 100-105% FTP · Zone 4-5 (Threshold/VO2max)
What this workout does
Tempo straight into hard threshold efforts with only short recoveries - the way races actually unfold. Teaches you to go hard when you are already working, not from fresh.
Starting hard efforts from tempo rather than from rest mirrors how races unfold, training you to hit 100-105% FTP with lactate already present. The short 90-second recoveries keep the aerobic system pinned, deepening the threshold stimulus rep after rep. Best in the final weeks before target events.
How to ride it
Indoor / trainer
Warm up 15min. 10min at 80-85% FTP straight into 3x5min at 100-105% FTP with only 90s easy between. Cool down 10min.
Outside
Pick a rolling circuit like a race course. Ride 10 minutes at 80-85% FTP as if sitting in the bunch, then attack the next section: 3x5min at 100-105% FTP with just 90 seconds easy between - legs burning, effort honest.

Classic 2x20
70-95 min · 69-84 TSS
The gold standard for building threshold power. Two sustained efforts that challenge your body to adapt at the intensity where fitness gains are greatest.
3x10 Threshold
50-70 min · 43-53 TSS
Three focused threshold efforts with generous recovery. Shorter intervals make it easier to hold good form and target power.
4x8 Threshold
56-85 min · 66-81 TSS
Four solid efforts at threshold. The shorter duration lets you hit the power target precisely - quality over quantity.
Over-Unders
46-77 min · 57-69 TSS
Alternating above and below threshold teaches your body to clear lactate while maintaining power - a crucial ability for racing and hard group rides.
Hill Repeats — Threshold
57-81 min · 49-59 TSS
Find a 3-5 minute climb and ride it at threshold. Climbing adds resistance naturally - a simple, effective way to build power outdoors.
Sweet Spot Intervals
65-85 min · 54-66 TSS
Classic sweet spot work to push your threshold higher. Challenging but sustainable - the most efficient intensity for building FTP.
