A real plan for
your Enduro 3.

The Enduro 3 is built for days out rather than hours: 63 grams, solar charging, and up to 320 hours of GPS. It is the watch you take when the race is longer than most people's training week. What it does not do is build the training that gets you to the start line.

What your Enduro 3 already gives you

• Up to 320 hours of GPS with solar, and up to 90 days in smartwatch mode
• Preloaded TopoActive maps, with dynamic round-trip routing
• Training Readiness each morning
• Trail run VO2 max, which adjusts for terrain
• Grade-adjusted pace for climbing
• An FDA-cleared ECG app

What it doesn't do on its own

• No ultra-specific plan out of the box
• Training Readiness scores the day but does not schedule it
• Nothing periodises a build-up across months

How to get a training plan onto your Enduro 3

1. Free option — Garmin Coach: Garmin Coach covers road-running distances on the Enduro 3. There is nothing for a 50K or a 100K, which is the exact reason most Enduro owners bought the watch.
2. Adaptive option — Custom Gains: connect your Garmin, tell the coach your goal in plain English, and it builds your week from your actual data and pushes each workout to your Enduro 3 — adjusting when you miss days or your recovery is low.

Beginner setup checklist for the Enduro 3

1. Set your max heart rate (or let it estimate) so your zones are right.
2. Wear it to sleep for a week so recovery metrics calibrate.
3. Pick a goal and run mostly easy (Zone 2) to build a base.
4. Connect a coach (Garmin Coach or Custom Gains) so workouts land on the watch.
5. Check your recovery each morning — if it's low, take the easy day.
