woman muddy raceSometimes referred to as a Tough Mudder, Warrior Race, Spartan Race or the original Mud Run, there are lots of other similar names and they continue to grow in popularity.
Whatever they may be called, these races all share many similarities. They all are an extreme test of your fitness, physically and mentally, through a race course designed with various types of obstacles – from monkey bars to dirt hills to cargo nets, mud pits and even barbed wires!
From test-taking to fitness or skiing, practice is undeniably vital to prepare oneself mentally, physically and even psychologically. In doing so, you would need a timepiece not just to track time but also to monitor your statistics and track any improvement. This is also the same reason why you should invest in a reliable watch as you practice for an OCR.
A good watch is needed not only during practice but all the more during an actual race. Aside from one that could tell time, you’d want a watch that will be able to track your fitness data such as heart rate, pace, and speed so you would have an idea how good or bad you’re doing.
In general, you should look for a watch that is as though as, or even tougher than, you.  Primarily, you should consider GPS watches that are very durable and water-resistant & mud-resistant.
Since you’d be going through various types of impediment along the course of the race, the materials of your watch should be strong enough to handle any accidental smash, pull or push and any other pressure that the watch and its wearer may encounter. It should not easily break, be torn or unclasped; otherwise, the ‘Spartan’ athlete will just be surprised that he or she no longer has a functioning watch.

Water resistant watches are no longer hard to find. Even stylish and fashionable timepieces can already withstand a certain water depth and pressure. However, that is not enough during the mud runs. OCR watches should be tightly sealed to ensure that no amount of sand, water, mud or any other foreign object will be able to reach the internal structures of the watch. As such, it should be also able to withstand thorough cleaning after the race.
In addition to those key features, you must also consider all those other features that you’d typically look for in other fitness and sports watch such as heart rate monitor, long battery life, built-in GPS, readability and water resistance (all of which we explained here).
With those in mind, the following are the watches that are worthy to look into if you’re into endurance races.

When TomTom was founded in 1991, it offered business-to-business applications such as meter and bar code reading. 10 years after, it produced its first car navigation products, and for these, TomTom has prospered. Since then, it has been producing a variety of navigation devices.
Evidently, compared to other brands presented here, TomTom is still new in the fitness arena. It was only in 2011 when it partnered with Nike to create a fitness watch. After which, TomTom has learned to produce its own watches.  In 2015, it announced a collaboration with the Reebok Spartan race and their GPS Sport Watch
Nonetheless, this one model from TomTom has been a popular choice for Spartan racers.

Lastly, the TomTom Spark Cardio + Music is worth mentioning especially for those who cannot survive the Spartan Race without music on.
With this watch, you can store up to 500 songs that you can play without the need of your phone. It also comes with waterproof Bluetooth earbuds so you do not have to worry if it gets splashed along the race. However, to accommodate this feature, it has become bulky compared to other multi-sport watches.
Also, it has been observed that it may be quite difficult to add new music to the watch and that most may find it hard to navigate the watch features.

What is OCR?

two competitor deep in mud during ocr race
Mud is one of the key elements in most OCR races, which makes mud-resistant watches a top pick.

If you’ve gotten this far, we assume you know what they are but just to clarify so we are on the same page: OCR stands for Obstacle Course Race. Many of the basic elements of the races have their roots in military training.
OCRs would certainly test your limits in every way possible. Some of these race organizers actually hire military personnel to help design the courses and many of the elements are similar to what you would endure during training or boot camp, but of course on a much smaller scale since these courses last a few hours compared to a full career in the military.
Some people have gotten away from the narrow focus of “obstacles” and refer to it as “Adventure Training”
If you want to know more about how you can prepare for a race, check out this training video by Scott Herman:
Before You Go
Entering a Tough Mudder run, warrior race like the Warrior Dash or Spartan race is no joke. It is not for those people who suddenly want to get into fitness and try what’s latest.
You cannot just search for a race and sign up for one that’s coming in a week. No, a week’s worth of preparation is certainly not enough to prepare you for any OCR, regardless if you’ve been to one or two races already.
Here’s a quick video to give you an idea of just how tough (and muddy) these races are.
Any athlete who intends to join an OCR should seriously do some planning, training, managing your diet and preparing your gear (including a watch of course).
These include gathering as much information as you can about the race – familiarize yourself with the obstacles and course conditions, know what the other athletes are saying, watch what you eat and make sure that you get enough nutrition that you need, and of course, prepare the things you need such as an appropriate outfit, gloves, shoes, hydration pack, and a tough watch.
