I did a sprint triathlon with a pool swim this morning and recorded it using the triathlon mode (customised to substitute pool for open-water swim). It knows I did 12 lengths and it knows the pool was 25 m long, but apparently I swam 8600 yards in just under 8 minutes. I'll see if I can report the bug, but what's the best way to handle this in my Garmin Connect stats? Can I delete this preposterous part of the activity? Can I correct the distance by hand? Are there any long term consequences if I ignore it? (I let Strava auto-set my max HR at one point only to discover some glitch had set a 240 bpm value at some point. That sort of thing.)
