Varying It Up: Measuring Distance

I wrote about the importance of planning new and different routes to break the monotony of outdoor exercise. Especially when following a running program that assigns runs of certain distances, it's useful to know the length of each possible route. There are a number of ways to do that.

First is past experience. If you travel this path once, with the aid of a pedometer, gps watch, fitbit, or smartphone you can tell or estimate its length. When I first started walking, I only had my Omron pedometer. It was nice because it counted my steps all the time, not only when I worked out. To estimate distance, I measured how many steps it took for me to walk or run a known distance. After repeating on several occasions, I'd have an idea of how many steps it took me to cover a mile, and use that to measure future walks / runs. It's not so accurate, but it works and is relatively inexpensive.

After losing my pedometer, my girlfriend got me a Fitbit. The Fitbit has the feature to measure distance, but it has to be connected to the phone in real time, which drains its battery quickly. I end up thus using it as a fancy pedometer, to track my steps, heart rate, and sleep. It is great for those purposes and I highly recommend it. However, for maps and accurate distances, I rely on my (free) RunKeeper app on my smartphone. RunKeeper makes things simple, as long as you remember to turn it on and off at the start and finish, and remember to pause / unpause when hiking. It also has a map editor online that I have used to create routes. For longer running routes, I turn RunKeeper on and do a survey with the bike or even the car. Biking an unfamiliar trail first is a good way to know the details of the terrain one will encounter on a run.

Those tools, however good, don't solve the problem of estimating the length of a new route ahead of time, for instance for travel.  For this, I use Google Maps. I illustrate below. (It is easier to do this from a computer rather than a mobile device.)

First, survey the neighborhood visually and find a trail you want to use.  Click on the map to insert a marker at the start of your route. Now click that marker and choose directions, selecting directions for walking (or biking, as the case may be).


Click under search destination, then click on the map near a point at the far end of where you want to go, and search. You will receive options for trails with a rough estimate of distance.


Finally, zoom out and adjust your trail by dragging point on its perimeter to where you want them. For more complex routes with overlapping pieces, I find it more efficient to measure each segment individually and add up the pieces separately.

Staying the Path

Sooner or later, every exercise plan stumbles upon obstacles, such as work demands, travel, weather, or injury. Following are the ones I encountered over the past five years. I will address each in turn in later posts, along with my response to each challenge. Finding the time to exercise. Schedule disruptions such as illness, travel or extended work commitments. Monotony: Boredom from doing the same routines and running over the same trails. Being a single-parent: I have shared custody of my daughter, which imposes the added challenge of integrating my exercise with my parenting.   Weather: a significant factor for exercising outdoors. Trail conditions: ice, rain, mud, potholes, construction closures, etc., can interfere with our planned activities. Injuries. Specific adaptations because of lifestyle. For example, I live in a townhouse, so end up doing stairs twice as often as usual, while my work involves sitting in front of the computer for long hours. These ha...

Exercising Outdoors

Had a nice one hour walk today around the lake. Under the towering trees shading the trail, I saw a caterpillar climbing a silk thread. Every day that I walk, run, hike, or bike outdoors, I see a small wonder of nature, be it a great blue heron wading in the pond, turtles sunning on a log, or deer almost perfectly camouflaged in the thickets. Last week, I saw a hummingbird hovering near a treetop, and a rainbow patch next to the setting sun. Over the years, I have seen red foxes and beavers. Caterpillar climbing on a silk thread. Every exercise session outdoors is an adventure. Even walking the same trail over and over, you see different things at different times of day, and as the seasons change. It is a refreshing way of breaking the monotony of exercise . For me, it wins hands-down over working out in a gym or a treadmill. Fresh air and Vitamin D are a welcome bonus, and being closer to nature is refreshing and healing. The outdoors often pose a challenge. Trail conditions a...

First Run in Weeks

The humidity over the last few weeks kept me mostly indoors. I walked here and there, but I couldn't even contemplate running in 90% relative humidity, even with cooler temperatures in the 70s. Yesterday, the clouds finally cleared up and a partly sunny sky invited me to go outdoors. First I thought about a long walk, but when I saw the humidity was down to 70%, I couldn't resist putting on my running shoes and heading out. Turtles basking in the late summer sun after days of cloudy weather. It was a good run, though more on the humid side, and a sweat bath when the wind is to my back. I ended up running 2.4 miles around the lake. The construction is almost completed on the opposite side of the trail, flattening out a severe 30-40 bank in the trail that was gradually steepened by erosion. The new flat trail is nice and so much easier on my ankles. Today, the main residual soreness is in my glutes. That's a good sign. It means the program I've been following to ...
