Best GPS Watch for Ultra Runs and Trail Running

Within the range of GPS watches that we stock at Outdoor GPS shop, there are a number of watches that stand out for us as the best for ultra running and trail running, the key things we are looking at are reliability, battery life & robustness.

In this series of articles we will review the main GPS watches in the UK.

Before doing this it is good to look at the key features to consider when selecting a GPS watch for ultra runs and trail running. Drawing on our team's firsthand experiences, including participation in events like the Montane Spine Race, we’ll share insights into what makes a GPS watch ideal for long-distance challenges.


Personal Insights from Ultra Running Events

We understand that individual preferences vary, but some essential qualities are universally valued in a GPS watch for ultra and trail events.

For demanding races like the Montane Spine, reliability, durability, and extended battery life are non-negotiable. The goal is to minimize charging concerns during your run and focus on the journey ahead.


Key Features to Look for in a GPS Watch

While every runner may prioritise different features, here’s a general list of the most important attributes to consider:

  1. Battery Life: Opt for a model with long-lasting battery life, capable of sustaining GPS tracking throughout your event.

  2.  Robust Build Quality: A GPS watch must withstand tough terrain, extreme weather, and the rigours of long-distance running.
  1. Mapping Features: Topographic maps, breadcrumb trails, and turn-by-turn navigation are valuable tools for trail running.

  2. Satellites/ accuracy: Reliable GPS tracking and navigation ensure you stay on course, especially in remote locations.

  3. Customisable Data Screens: Access key metrics like pace, distance, elevation, and heart rate at a glance.

  4. Screen quality: Look for a colour screen and there are different screen types, MIP often give better battery life, but a Amoled screen makes for a brighter screen and more vibrant colours

  5. Value for money: GPS watches vary massively in price, so we look at what value you get for each pound your spend.

Our Experience

From personal use in ultra races, we've tested various GPS watches and found that each offers unique advantages. Whether you're tackling a multi-day event, or a single-day trail run, the right GPS watch can significantly enhance your performance and confidence.
