Seat Summit #23 (fenix 3 f/w 3.60 & GPS 2.90) - Derek Paton's 4.6 mi run
Wow - very promising update by Garmin.  The acid test will be my bog standard 4.17 mile loop but this track looks pretty fantastic.  Tracks pretty much spot on on the Arthur's Seat paths I took.  Altimeter is spot on too (manually calibrated and auto calibrate off)
