[Case Study] I ditched my GPS watch while training for a half marathon, here’s how I finished

Vancouver Lake 1/2 Marathon

Have you heard of training by feel, running with your inner GPS or simply training without a GPS watch? They’re basically the same, but I had never tried this strategy myself, until the last 5+ months. Last Sunday, I crossed the finish line of the Vancouver Lake Half Marathon and I saw the finishing time of my run for the first time since last September. In this article, I will briefly tell you what I learned, how I trained and the results of my race.

Training With a GPS Watch or Electronic Stopwatch

Since 2010, I’ve religiously tracked every run that I completed outside. I uploaded runs to my Garmin Connect, Polar Flow or Strava Accounts. Prior to 2010, I used a simple digital stop watch (traditional Casio) and documented the results in a log book. I was never obsessed with my times, but I would compare similar workouts from year-to-year.The GPS watch was merely to ensure I was following the assigned workout paces. I wasn’t typically concerned about distances, since I’ve been running in/around my town for the last 19 years, I know the approximate distances.

Running By Feel

In Matt Fitzgerald’s book: RUN – the mind-body method of running by feel, he provides numerous reasons to ditch the gadgets and listen to our body. The biggest reason to run by feel, as opposed to increasing/decreasing your pace mid run, based on what you see on your GPS watch, is that how you feel during runs is the most reliable indicator of how well the training process is going. Many who run without a GPS watch claim that it reduces performance pressure and can help prevent injury, because when they make adjustments to their pace based on how they feel, they’re not over-extending themselves. Instead, they’re actually working within a smart, yet challenging, training zone.

So, if you feel good during a run, you’re likely fit. In general, the more fit you are, the better you will typically feel during your runs. Now, I understand that if one was running slow, they may feel good, but that doesn’t mean that they’re fit. So, let’s assume you need to be running at what is a fairly quick pace (within your abilities) and then determine how you feel. Ultimately, the only way to get fit is to work hard, which likely means you’ll end up suffering through some workouts.

Remove the Watch To Create A Positive Mindset and Momentum

Momentum in running, occurs primarily in training and can take the form of a period of improving fitness. In many articles and interviews, it’s apparent that even the most confident athletes know that they do not have complete control over every situation. They are aware that their success often depends on the situation shaping itself to their benefit. Why not remove the watch from the equation and simply run by feel where you can create both a positive mindset and momentum.

In my experience, with runners I coach, the most effective way to manage their fitness/fatigue balance is to tell them to pay attention to how they feel. When they don’t feel good, regardless of the time/pace on their watch, we must must determine whether it’s because of lack of fitness or excessive fatigue. If it’s lack of fitness, we can correct this with more hard work. However, excessive fatigue should be corrected by more rest, which also could mean simply slowing the pace of the workout and upcoming workouts.




Another term for running by feel is “using your inner GPS.”  Some coaches, like McMillan, have written extensively about calibrating your inner GPS, so I won’t get into the details in this post.  It’s important to understand that inner GPS training or running by feel should not take the place of traditional time/distance-based training.  At least not until you have a lot of experience running by feel. I recommend that if you want to run a time like 1hr 59 minutes for ½ marathon, you better know exactly that pace.

Heart Rate Monitor

If you don’t feel completely comfortable about ditching a gadget, an alternative to using a GPS watch is using a heart rate monitor.  You’ll still need the watch, but you can just adjust it so you only see your heart rate.  One could make a sound argument that this is technically running by feel.  Instead of running at preassigned paces that you monitor with your watch, when you train with a heart rate monitor, you simply adjust your pace by keeping your heart rate within a specified zone. This is why this is also referred to as zone training.  I discuss how to train using a heart rate monitor in an article I wrote a few years ago.

My 5 Month Challenge of Training without a watch

What started out as just running my base/easy mileage without the watch, soon turned into 5+ months of not tracking my times or pacing for any training run. The majority of my runs were on the road, some were on hotel treadmills.  Typically the treadmill runs were 4 – 5 miles at an easy/conversation pace (low 7s) and an elevation of 1.5 – 2 degrees.  Duration of my treadmill runs were 30 – 40 minutes. Over the first 3 months I usually ran 18 – 30 miles per week at an easy or conversation pace.  I don’t know for sure the pace of any runs, but for the last 5+ years, I’ve been able to easily complete 6 mile runs between 46 – 48 minutes.

To a large extent, due to my many years of experience of being a long distance runner, my inner GPS has been calibrated.  I’m confident that I was probably running the majority of my runs at 7:45 – 8:15/mile pace.  As you can see below, I also completed a few faster/tempo paced runs of 5-6 miles. On a weekly basis I would also get to the track to complete strides to keep my legs moving faster.




Since last September, while I completed my base or foundation training, I also performed 2 – 3 different CrossFit workouts per week. The CrossFit consisted of 45 minute High Intensity Interval Training (HIIT) with a variety of challenging body weight exercises. I also regularly completed a 45 minute routine where I would rotate between 1 minute on a stationary bike at a controlled to vigorous pace with 1 minute of body weight, BOSU and/or barbell exercises. The key to these workouts was the variety and intensity.  They were supervised by a personal trainer in a group setting at my health club.  My goal was to get stronger, build an injury resistant body and reduce the pounding on my legs while completing aerobic exercise.

Increasing the Intensity as the Race Gets Closer

Two months out from the ½ marathon, I started to gradually increase my weekly long run from 7 to 12 miles. I also increased the intensity of 1-2 runs per week.  All the while, I never used a GPS watch.   Following are some of the workouts that I completed:  Training started in September. During Weeks 1-4, I continued with base training (conversation pace runs of 4 – 7 miles) and cross-fit training.

Week 5 of 10
8 miles at easy/conversation pace (CP)
Fartlek
3 other easy/CP runs of 4 – 6 miles (1 day w/ strides)

Week 6
10 miles at CP
4 mile Tempo (at ½ Marathon Pace (MP))
3 x CP runs of 4 – 6 miles (1 day w/ strides)

Week 7
11 miles at CP (last 2 miles at ½ MP)
6 mile Tempo (at ½ MP)
3 x CP runs (1 day w/ strides)

Week 8
12 miles at CP (last 3 at ½ MP)
Track Workout – 4 x 1600M at 10k Pace
3 x CP (1 day w/ strides)

Week 9
10 miles at easy pace (last 3 miles at ½ MP)
Track Workout – Ladder (400M, 800M, 2 x 1200M, 800M, 400M at 5k pace)
3 x Easy Runs

Week 10
9 miles at easy pace (last 4.5 at ½ MP)
4 x CP 4-6 miles (2 days w/ strides)

Race Day – February 24th

Because I didn’t train too hard for this race, I wasn’t sure what kind of time to expect. The last ½ marathon I completed (2 years ago) was 1:27:45. I figured anything around 1:30 (6:55/mile pace) would be great. With almost ideal conditions of 35 degrees, overcast and no wind, I positioned myself at the start, slightly behind some runners who were projecting finish times of 1:25 – 1:28 (6:30 – 6:45/mile pace).

My strategy wasn’t to try to keep up with the faster runners. Instead, I wanted to keep them within range (gradually let them get 3-4 minutes in front of me). Turns out, this is exactly how the race played out. There were no splits given at any point, so I only knew my time as I approached the finish. My finish time was 1:30:25.

Training without GPS watch

After the race I spoke with others who had run near me and told them that I had not used a watch for the last 5 months. Overwhelmingly, the response was positive and a few thought “how liberating.”

Lessons Learned

It really was liberating to train without a watch. However, I think I would use a watch for longer runs & track workouts if I was really concerned about achieving a goal time. The key to being successful when you’re not training with a watch is to be honest with yourself and push during the hard workouts and of course during the race. I knew I was getting fit when I was able to comfortably push the last 4.5 miles of my 9 mile run the Sunday before the race.

Due to some tough weather in January, I condensed the timing of the strength & track workouts (typically they start 8 weeks out), I never worried about splits during any of these harder runs. My goal was to self calibrate what I thought were 5k, 10k, ½ and full Marathon paces during each of the tougher workouts. During each one I always felt like I could have gone further or completed another interval at the desired pace. This doesn’t mean that I wasn’t running fast enough, because I felt fatigued.

I’m certain I could have run faster in the race if I had a 6 or 8 mile split. Also, if I included more strength and interval workouts in my schedule, I would have benefited. I also believe that if I had used a GPS watch during the race, I would have pushed the pace a bit more during the middle and end to get under 1:30.

Why You Should Run The Vancouver USA Half or Full Marathon

Vancouver USA Half Marathon

The Vancouver USA Marathon was voted top 10 New Marathons by Runners World. It’s a great small town marathon and among other claims, it’s the only marathon with a Summer Brewfest and it enjoys a relatively inexpensive under $100 registration fee. I ran the half marathon slightly over a month ago, but I wanted to provide a race recap and discuss some of my training leading up to the race.

I last ran this race at it’s initial running in 2011. My time back then was 1:28:18, which placed me 6th among Masters (40+) and 29th of 1,427 overall runners. In 2016, there were not as many participants and I didn’t run as fast, finishing in 1:31:29 which was good enough for 10th overall males and 14th of 1,161 total runners. Although, I’m 5 years older, I was hoping for a better time (especially because I ran 1:27:59 earlier this year). The course is USATF certified and has a lot of uphills. Start and finish are at the same location, so it’s a net 0 incline, but the last hill at mile 12 really gets your legs. I can’t imagine what it feels like for those completing the marathon (which finishes alongside ½ marathoners for the last 11 miles).

I usually post my splits, but I’m having problems with my Garmin Forerunner GPS watch (it won’t sync up to the Garmin Connect site). I observed that at most miles I was running 6:55 to 7:05 pace, which is right inline with my finishing time.

Unfortunately, I came down with a bad cold at the beginning of the week. My frequent business travel finally caught up to me. Although I rested most of the week and ingested about 5 times the recommended daily allowance of Vitamin C per day all week, I don’t think my body was fully recovered by race day.

Enough with the excuses….the Vancouver USA half and full marathon are great races. Bart Yasso from Runner’s World attends every year and helps to promote the event with pre-race shakeout runs and talks. Race day weather this year was perfect (sunny and low 60s). There’s many helpful volunteers throughout providing water, Gatorade and even energy gels. The course is well marked and there’s plenty of spectators cheering racers on. The mid June timing of the race fits well for anyone training for a Fall marathon. I also enjoy how close the race is to where I live and the fact that I can park about 3 blocks from the start (so I don’t have to stand in a line and check a bag).

The organizers are strongly considering moving the race to September. They’ve taken some surveys and observed slightly declining registration over the years. The concern is that the race interferes with Father’s Day and graduation activities. Personally, I think that with the race finishing in the morning (as most do), conflicts shouldn’t be an issue, but that’s my biased opinion and evidently not how others feel.

Training Notes:

This was the first race that I incorporated a 9 day cycle into my training. You can read about this concept in a post I wrote a few months ago.  Because I view this race as more of a training run near the beginning of my marathon training, I didn’t start my longer (10+ miles) runs until about 45 days out from race day (beginning of May). I completed 2 x 10 milers, 1 x 11 mile and 1 x 12 mile run. I also completed 3 tempos of 6-10 miles (each with 1 mile warm-up and 1 mile cool down). My track work consisted of 3 sessions where I completed a combination of 200m, 400m, 600m and 800m ladder style workouts to improve my speed. A week before the race (just when I was starting to feel like a cold was coming on), I completed a track workout where I ran 2 x 2 miles at 12:50 and then 12:38. I completed strength work in the gym once per week and plyometrics/body weight exercises another time each week. Overall, I was pleased with my workouts and conditioning. I think that I was simply worn down from all my travel and my illness.

Lessons learned:
1) Get more sleep in the weeks leading up the race.
2) Run more tempo/lactate threshold runs at ½ marathon pace, which will help my marathon pace

Vancouver USA Half

I hope this race doesn’t move to September, but if it does, it may be reason for me to run the marathon instead of the half. I enjoy training for Fall marathons (primarily because the weather makes it easier and the long days give me more flexibility to run early in the morning or later in the evening). Regardless of when the 2017 will be held, I strongly recommend you consider adding the Vancouver USA Half or Full Marathon to your schedule. Registration fees are low and value is high.

Let me know if you’re going to be in town to run this race, I would love to link up and complete a pre-race run a day or 2 before.
