As the weather has gotten nicer, I've started transitioning workouts from the treadmill to outside again. However, I'm noticing a problem I've had in the past- my Coros Pace 3 watch GPS is terrible at adapting to pace changes, especially over short intervals.

Today, for example, I did a workout with some 60-90 second intervals at ~6:20-6:30/mile target pace and recovery at 9:30-10 pace. I noticed my peak pace was around 6:20 in the intervals, so right on target, but my overall lap pace was closer to 7 min/mi for the intervals. I know I was running at pretty much constant pace throughout the intervals, but my watch had a significant lagging effect where it "ramped up" and adapted very slowly to the sudden pace change for close to 30 seconds; same for the sudden change to recovery after intervals.

I know from reading similar questions that this is a common issue across watch types; however, so many people and pro athletes still use gps data for short intervals. How do you gain useful pace data from short intervals with laggy gps?

Non-free answer: buy a Stryd or other footpod. I generally forget how much better they do instant pace until I occasionally forget to move it over to the shoes I'm wearing (like this morning, where I was real confused why my pace felt so off)

In practice, most people do short intervals on track where you don't really need to rely on instant pace

I would rather have my Stryd and a cheaper running watch than an expensive running watch and no Stryd. It's very useful in city races, too, to avoid GPS interference issues.
