A little dome running analysis

Sometimes in the winter months my wife and I decide to retreat to the comfort of running inside a fieldhouse dome. We love running outside in the winter, and the cold doesn’t bother us, but sometimes the conditions are just too severe. Often we’ll do a nice long run outside on Saturday, and then head over to a dome for a nice recovery run on Sunday. Or other times, if the trails and roads are too icy we’ll opt for as many loops as we can do inside a dome.

Thankfully, most GPS watches function inside domes, so you don’t need to resort to counting laps. However, not all domes are created equal. In the past couple months we’ve visited two different domes and have had a chance to see what they look like from a GPS tracking perspective.

First up is our favorite dome, the Plymouth Fieldhouse. This dome is just over 5 laps to a mile, and it’s a nice comfortable temperature almost all winter long. If you look at the GPS track, it’s actually pretty darn good. Almost all of the GPS lines stay within the borders of the building.

However, sometimes their hours are more limited than we would like to deal with. There’s another dome down in Edina called Braemar Field. It’s just over 4 laps to the mile, and often has a wider range of open times.

However, there’s one slight issue with it’s GPS tracking.

As you can see, it’s tracking is quite a bit off, but especially on two corners (NW and SE). What’s interesting is that on those two corners of the dome are their surveillance cameras. When you run past those corners you can see two little domed cameras hanging from posts. I’m not sure if they’re wireless or not, but I’m betting there’s something in there that’s throwing off the signals from the satellites.

Its not like the rest of the track is perfect, but it’s wild to see the deviation on those two corners on almost every lap. Overall though, it’s awesome to have these great resources available. Being able to toss aside the wool socks and jackets, and just run in a thin shirt, once in a while, is a ton of fun and a great change from the day-to-day of cold. I certainly wouldn’t want to do a marathon in here, but for a simple training run, it’s awesome.
