ERG mode is useful. It can also make every indoor ride feel the same.
Strappo starts with the road, so workouts have to fit around that. A structured session can sit on top of a route, but it should not erase the route. Warmups, recoveries, climbs, and descents still have shape. You are not only staring at a watt target. You are riding a stretch of road with grade, distance, and rhythm.
That matters most when the route is longer than the workout. A 45-minute threshold set should not make you ride half an hour of dead approach just because the road file starts there. Strappo maps the workout into a useful route window, then keeps the interval train together. The session still has targets. The road still has a beginning, middle, and end.
Apple Watch is for small changes in the middle of the work. Toggle ERG. Nudge the target with the Digital Crown. Keep the phone on the map instead of turning the ride screen into a control panel.
The ride record still matters when the session ends. The point is not a sterile trainer file with a few target watts. The point is a complete indoor ride: the route, the elevation, the work, and the decisions you made along the way.
Targets are useful. The road is still the point.
