Measure for measure, I don't like this change

New and improved?
Today's run (street): 5 miles

In business, many people subscribe to the idea that, "if it ain't broke, don't fix it." I made my career challenging that notion and I firmly believe (at least in technology) that complacency is the enemy of success. Okay, no more clich├ęs, but I do believe that open source technologies further the cause of progress. So am I a hypocrite to condemn the new Gmaps version that just went up, using OpenLayers in place of the Google Maps API?

I've relied on Gmaps for years as a tool to precisely measure my routes. Foot pods and GPS watches/apps both fall short due to calibration, route angles or weather. I always use mapping, combined with time, to calculate my exact pace. This morning I was surprised to see a new interface for Gmaps. I also discovered that Gmaps is now an open source supported framework, and will now be called Milermeter. It wasn't until I tried mapping this morning's run that I started to grumble.

I won't go into the specific issues that I had, but I will say that the interface can use some refinement. I'm not sure of the reason, but items flicker on screen and the tools behaved inconsistently. I'm also unsure about the accuracy. I mapped my route using "Milermeter" with both Chrome and Firefox and saw a 1.5% difference in distance between them. Both measurements fell short of what my Garmin captured, surprising because that usually under-counts distance.

Forgetting the technology issues for a moment, this morning's run turned out to be a really good workout. I ran over to the business park to run the loop a few times. This route offers either a steady uphill for almost a mile, or a shorter but steeper section if you run it in the opposite direction. I took the steeper option and made three circuits before heading home.

I used my metronome app and set it to 87 SPM. Although I felt I was coordinating my steps with metronome, I didn't end up with a particularly fast pace. To be fair, except for the hill, I didn't push that hard, although I kept a steady stride throughout the run. Right now, I care more about managing up my cadence than speed. If I understand how this all works, better paces should follow
