This is a high quality, triathlon sports watch and activity tracker that will cover most of the features you need for training and racing.
Positives: It looks great and you have to look hard at it to find bugs. The MOVESCOUNT ‘data ecosystem’ is very good and fairly open with some novel and useful features.
Negatives: It only supports Bluetooth SMART sensors. What it gains in being a 24×7 watch it loses a tad in size/weight.
Comments: There is still plenty of work to be done matching the features of Garmin. Although when you get all those features you will find few that you use. There is likely to be a 2015/2016 upgraded version to extend the range.
Alternatives: This link covers some alternatives.
Detailed Review: This link covers my first review of the AMBIT 3 and then I look at functionality in a more detailed triathlon-specific review of the AMBIT 3 SPORT.

My favourite kit and nutrition
- Maurten — the race nutrition trusted by elite athletes. Gels and drink mix engineered to be easy on the stomach.
- Garmin 90-degree charging adapter — the small adapter that keeps your charging cable tidy at the stem. Essential for race day.
- Garmin charging puck — the fastest and most reliable way to top up your Garmin before a session.
- Ravemen FR300 — front light that mounts directly under your Garmin or Wahoo head unit. Keeps your bars clean and your beam pointed where it matters.
- Garmin Varia RTL515 — radar rear light that alerts you to vehicles approaching from behind. Pairs with your Edge or Garmin watch.
- Stryd — the footpod that brings running power to your Garmin. The single most useful running upgrade I have made.
- Favero Assioma Pro RS2 — the power meter pedals most serious cyclists end up choosing. Accurate, easy to move between bikes.
