Garmin Enduro

£649.99, garmin.com

If feats of lengthy running, cycling, climbing or swimming endurance are your fitness bag – or you just hate charging your watch – the rugged Enduro is an excellent all-rounder. Its full GPS battery life promises up to 80 hours, extendable to 300 in lower accuracy UltraTrac mode. Solar skills help slow the burn rate and even with an hour-a-day’s training you’ll only need to charge this once a month.

Beyond that mega battery, its training and fitness tools include suggested daily workouts, fitness performance tracking with VO2 Max, a recovery time advisor, heat and altitude acclimation, plus sleep, stress, hydration, breathing and blood oxygen monitoring.
