As we roll out RIDE Release 39 – Thriller, here's a clear breakdown of how it differs from our last season and what that means in class.

("Breathe") sat in a grind profile - while RIDE Release 39 ("Thriller") moves toward concentrated intensity and sharper peaks. It's more volatile, more dynamic, and built around surge intervals and cadence-generated effort.

We are expanding the programming range.

Performance Snapshot

Duration RIDE 39: 48:13 vs RIDE 38: 48:15

RIDE 39 runs virtually identical in - albeit two seconds shorter.

Total Work (Revolutions) RIDE 39: 3,392revs vs RIDE 38: 3,482revs

RIDE 39 produces its output in fewer revolutions - the effort is more concentrated, not less, while having options to achieve more with the ACC.

Average RPM RIDE 39: 70rpm vs RIDE 38: 72rpm

RIDE 39 runs marginally slower on average - but you have the ACC options ahead of you to find MORE. RIDE 39 produces its intensity through sharper, concentrated load spikes rather than the sustained cadence you'll find in R38.

Effort Distribution

• RIDE 39 concentrates its intensity into shorter, sharper efforts - some sitting inside longer working blocks.

• Moderate "tempo" time is almost halved. RIDE 39 doesn't spend much time in the middle - it's either working or it's setting up the next one.

• When RIDE 39 goes, it goes. Track 3 (Climbing) hits L11 - the most load adjustments found across either release - and runs 6:30min. That's where this release earns its name.

• Track 5 (Race Endurance) generates effort through speed & load - 130 RPM at L2–L4. A different kind of hard. Add ACC to get ahead and you've made some new magic at pace.

RIDE 39 feels sharper and more dynamic. The surges are real. The recovery between them is what makes the next one possible.

In Practice

RIDE 39 builds power output through concentrated surge intervals across a wider RPM range (62–130) - with options to train ABOVE 130 on any 1:1 prescription.

Its most demanding cuing block hits early - prepare Track 3. The intensity arrives before riders expect it. Know where you're taking them before you get there.

When you launch RIDE 39, trust the structure. The surges earn their recovery. Hold the room through the peaks - don't rush the reset, don't oversell the climb. Let it build.

Let RIDE 39 sharpen what we built in 38 - endurance lays the foundation, power tests it. Your riders need both.
