Segment Hunter on long segements

Hi. I’ve got a quick question about the Segment Hunter datafield. I’ve got a race coming up in a few weeks and wanted to use the datafield to help with some pacing during the event. I noticed that someone on Strava has created a segment for the entire ~100km rolling route. Will Segment Hunter work on such long segments (where average power is likely to be below TP) or would it be better suited to picking a few shorter segments for key climbs/sections on the route?
Thanks

To answer your question, it won’t work for super long segments, no.

What you might try instead is to sync some of the shorter segments (climbs, etc.) on the route and use the “Tough. But not a breakthrough” pacing option. This will help you push harder on those segments, but won’t bring you to breakthrough/failure, which you probably wouldn’t want to do on a ~100km route!
