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.

Xiaomi Smart Band 9

AMOLED always-on at under $40

Most fitness trackers at this price use basic LCD displays. The Smart Band 9 brings a vivid AMOLED always-on screen — rare at this price point.

14-day battery with health monitoring

Continuous heart rate, SpO2, stress, and sleep tracking — all running for 2 weeks before charging. Most smartwatches last 1–2 days.

Works with iPhone and Android

Full functionality on both platforms via the Mi Fitness app, including notifications, sleep analysis, and health trends.
