Why buy each?

COROS Apex

75 hours GPS, 45 days typical

Enough for 3-day mountain stages without charging — a critical advantage for ultra-distance racing.

Full topographic maps

Breadcrumb + full TopoActive-style maps for turn-by-turn navigation on trails, mountains, and roads.

Titanium case and sapphire glass

Lightweight yet scratch-resistant materials that hold up better than most competitor watches at this price.

Polar Vantage V

ECG on a sports GPS watch

Polar Vantage V3 is one of the few sports GPS watches with on-demand ECG — usually only found on lifestyle smartwatches.

Wrist-based running power

Running power measurement without a foot pod or chest strap — a significant training metric for pacing effort on hills and varied terrain.

Polar Training Load Pro

The most detailed training load analysis in any sports watch: muscle groups targeted per session, recovery status per muscle, and long-term load trends.
