I swam using a Garmin multisport watch (910xt), but had it set for a 25 yard pool, then discovered it was a 25 meter pool... is there any way to edit the pool length in Garmin Connect post-workout?
You can change in Connect too but a bit fiddly - change activity type to uncategorised whilst in edit - then change back to lap swim and you then can change distance pool length etc and save it
