A running watch dying at kilometer 25 is the kind of nightmare you only need to experience once.
During my first attempt at a 32-kilometer run, my Samsung Galaxy Watch 7 suddenly ran out of battery. One moment it was tracking my pace and distance. The next moment, the screen went dark.
No data. No pace guidance. No record of the effort.
It felt like the run vanished.
That moment forced a realization. If I want to train seriously and eventually finish a full marathon, I need a watch that is built for endurance, not just a smartwatch that happens to track runs.
So I spent weeks researching. I compared features, battery life, price, and long-term usefulness. One watch kept showing up in runner discussions and reviews.
The Coros Pace 4.
In the end, two things convinced me: price and features. It offers serious running tools without the painful price tag of many sports watches. And it promises the kind of battery life that can survive long runs and marathon training.
Today, it faces its first real test.
The watch will debut during the 21-kilometer race at the TCS Clark Animo International Marathon.
Let’s see how it performs.
The Problem With Using a Smartwatch for Long Runs
When Your Watch Dies Mid-Run
Smartwatches are great for everyday life.
Notifications. Music. Apps. Messages.
But long-distance running exposes their biggest weakness.
Battery life.
During my first 32-kilometer run, my watch died before I even finished the route. The Samsung Galaxy Watch 7 simply could not keep up.
And that creates several problems:
- You lose your run data.
- You lose your pace monitoring.
- You lose your distance tracking.
For runners training for longer races, this matters a lot.
Marathon Training Requires Reliability
If you are preparing for a marathon, your long runs will often reach:
- 25 km
- 30 km
- 35 km
Those runs can last 3 to 5 hours depending on pace.
A watch that struggles with battery life is not just inconvenient. It becomes useless for serious training.
That experience pushed me to start looking for something designed specifically for runners.
And that search led me to sports watches.
Weeks of Research: Finding the Right Running Watch
The Criteria I Used
I did not want to buy a watch that I would replace in a year.
So I focused on a few important factors:
- Battery life
- Accurate GPS tracking
- Training features
- Price
Many sports watches deliver excellent features, but the price can be intimidating.
Some models easily climb above ₱20,000.00 to ₱35,000.00.
For a recreational runner building toward a marathon, that felt excessive.
Why Coros Kept Appearing in Runner Discussions
During my research, one brand kept appearing in forums and reviews.
Coros.
Runners praised several things about their watches:
- Extremely strong battery life
- Lightweight design
- Reliable GPS tracking
- Competitive pricing
The brand is less flashy than bigger competitors, but many runners swear by it.
Eventually, one model stood out.
The Coros Pace 4.
Price Meets Practical Features
The watch struck a balance that felt right.
It is affordable, but still designed specifically for runners.
Some of the features that appealed to me:
- Long battery life suitable for marathon training
- Lightweight build for comfort during long runs
- Running metrics that help track progress
- Simple and focused interface
It felt like a watch that prioritizes performance rather than distractions.
And that is exactly what I wanted.
The First Real Test: A 21K Race
Race Day in Clark
A watch review in training runs is one thing.
A race is another.
Tomorrow, the TCS Clark Animo International Marathon will serve as the first real test for the watch.
I will be running the 21-kilometer half marathon distance.
Races are the perfect testing ground for a sports watch because they push every function at once:
- GPS tracking
- Pace monitoring
- Distance accuracy
- Battery performance
And of course, the most important part.
Finishing the race strong and injury free.
What I Want to Learn From This Run
This race will help answer several questions:
- Is the watch comfortable for long runs?
- Is the GPS accurate during a race?
- Does the interface make it easy to check pace while running?
- How much battery does it consume during a half marathon?
A single race will not answer everything.
But it will reveal a lot.
Looking Ahead: The Road to a Marathon
Why This Watch Matters
Buying a running watch is not just about gadgets.
It is about consistency.
A good watch becomes part of your routine.
It tracks your progress. It records your effort. It shows how far you have come.
For runners chasing bigger goals, those numbers matter.
The Bigger Goal
The real objective is not just a 21K race.
It is something bigger.
A full marathon.
Training for that distance requires months of steady effort. Long runs, early mornings, and many kilometers on the road.
A reliable watch becomes a quiet training partner along the way.
Hopefully, the Coros Pace 4 will be that partner.
We will find out soon enough.
Final Thoughts Before the Race
The watch is charged.
Shoes are ready.
Race bib claimed.
In a few hours, the 21-kilometer run at the TCS Clark Animo International Marathon begins.
This will be the first real test for the Coros Pace 4.
And hopefully, the first step toward something bigger.
Wish me luck.
