Why buy each?

Garmin Forerunner 170

Training Readiness at entry level

Training Readiness, full Training Status, and wrist-based running power — analytics previously reserved for Garmin's mid-range — now on a $299.99 watch.

AMOLED display and 10-day battery

A bright 1.2" AMOLED touchscreen with a traditional 5-button design, up to 10 days of battery in smartwatch mode and around 17 hours of GPS.

Garmin Pay and 80+ sports apps

Contactless payments arrive on the entry Forerunner for the first time, alongside 80+ built-in sports apps and Garmin Coach adaptive training plans.

WHOOP 5.0

WHOOP Age — healthspan tracking

WHOOP 5.0 gives you a biological age score derived from your sleep, recovery, and training habits — showing whether your lifestyle is ageing you faster or slower than your years. Updated daily, it makes long-term health trends visible at a glance.

AI Coach — coaching, not just data

WHOOP's AI Coach learns your body's patterns and delivers personalised daily recommendations in plain language — not just what happened, but why, and what to do next. It adapts to your training load, sleep debt, and recovery trends.

Strength Trainer — weight room coverage

WHOOP 5.0 added a dedicated strength trainer that auto-detects sets, measures neuromuscular load alongside cardiovascular strain, and shows recovery demand from resistance training — a gap every previous WHOOP version had.
