Suunto Ambit 3 Review

IMG_3426This 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

  • Injinji – Runners protect your toes. Avoid discomfort and minor injury. Run more. Run faster. I use them.
  • Garmin 90-degree charging adapter — The small adapter that keeps your charging cables tidy. Essential for race day. I use one.
  • Garmin charging puck — the fastest and most reliable way to top up your Garmin before a session. I use one.
  • 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. I use one.
  • Body Glide – The blue anti-chafe stick that all swimmers and many runners use. I use it.
  • Maurten — The race nutrition trusted by elite athletes. Gels and drink mixes engineered to be easy on the stomach. I use them.
  • Garmin Varia RTL515 — A radar rear light that alerts you to vehicles approaching from behind. Pairs with your Edge or Garmin watch. I use this model.
  • Favero Assioma Pro RS2 — The power-meter pedals most serious cyclists choose. Accurate, easy to move between bikes. I use this model.
  • Garmin Forerunner 970 — A serious choice for a pro-grade triathlon watch. I use this.
  • Polar H10 — My daily driver for accurate, waking HRV readings.
  • Wahoo ELEMNT Roam 3 — The bike computer that has the feature Garmin lacks: usability. I use mine on most rides.
