Route source: official 2024 Maybank Bali Marathon course (plotaroute GPX), start/finish at
Sukawati, looping north to Gianyar, east toward Semarapura, and back along the southern coastal arc.
Elevation is smoothed from the GPX (~239 m gain full / ~131 m half); your Garmin reads ~215 m
— barometric/DEM models vary, but it's a gently rolling, mostly flat course. 2026 route assumed similar;
verify against the official map on release.
