What is a Spartan Race or an OCR?

A Spartan Race is a type of obstacle race designed to truly challenge runners and athletes. They vary in length from 5 kilometers to full marathons and can include any type of impediment, including walls, dirt hills, and monkey bars that need to be used to cross sections.

A lot of people participate in this type of race and undergo months of training to become healthy, fit, and strong enough to stand a chance. A person’s watch additionally needs to be able to handle the challenges of this type of run.

This video accurately demonstrates the numerous elements your watch will need to handle during a Spartan Race:

When entering a Spartan race, a watch can be significant for helping a runner determine when they are pushing their limits or if they are losing time.

But considering how many features these devices have nowadays, how can you be sure you have the right one?

If you would rather skip right to the comparisons, here is a simple table that should help you. Continue reading for more in-depth analysis. Here's your answer... 

Why is a Watch Important 

As mentioned earlier, many runners rely on their watches to not only track time, but to also keep track of their fitness and personal records.

Most modern devices can be considered trainers that monitor health and wellness by keeping statistics and warning wearers if they are pushing themselves too hard.

1. Studies published by the Department of Psychiatry at Columbia University found that running, especially over a long distance, increases the endorphins in the body

Endorphins are a pleasurable response to an activity, which makes it more enjoyable and a person more likely to continue to do it. Unfortunately, these endorphins can also mask pain or the harsh realities of exercise.

2. Heart rate monitoring is important, especially for athletes over the age of 35. A person’s maximum heart rate is a person’s age subtracted from 220.

This means a 30 year old runner should not go above 190 or else they put themselves at risk of too high blood pressure and other ailments.

Scientific American and the American Heart Association (AHA) recommend doing exercises that are between 50% and 85% of a person’s maximum heart rate.This means the above 30 year old should not have their heart rate rise above 161 beats per minute.

It might not sound like a lot, but your heart would need to beat almost three times in a second to reach this level.

3. Most modern watches can therefore help runners make sure they aren’t running too hard or putting themselves at risk of a heart attack or chest pain.

Another benefit of the watch during something like a Spartan race is simple time tracking.

Most runners enter competitive runs with personal goals in mind. If you can’t monitor your time, how will you know how well you are doing, if you need to speed up, or if you need to slow down? Simply put, you won’t.

The watch helps keep you in check and can often be a form of encouragement for individuals who strive for personal success.

4. For those who want to lose weight or burn fat, a digital calorie counter will also be a helpful tool.

So, the reason a runner will have a watch during a Spartan race will vary, but most use them. If you would like to find the best watch, check out the following examples below.

Each one has a different price point and packs different features, but all are beneficial for the average athlete.


You want a watch as tough as you when you run a Spartan race. These options provide runners with a range of prices as well as different strengths and weaknesses. The best way to tell if a watch will work for you is to try it on and see how comfortable you feel. It’s important to be your best self before heading out on the course.
