Map of 50 regional cycling subreddits using Current Metropolitan Statistical Areas (MSAs) for US cities and Census Metropolitan Areas (CMAs) for Canadian cities. Activity data from the past 6 months. Work in progress.

This a map of all of the places that I know of (or could find with a little googling) in Michigan that groom trails for snow biking (when conditions allow, of course). This list is as inclusive as possible meaning that if I have ever heard or read of a trail being groomed it is on here (even if it was groomed once back in 2016). Click on a circle marker to see the trail name and a link to information about current(?) trail conditions. Please comment (https://www.reddit.com/r/MichiganCycling/) with additions and corrections if you know of additional trails or better links. Thank you.

Interactive map showing differences between the 2021 Marji Gesik 50-and 100-mile courses and course used in 2018 and 2019. For both races (50 and 100 milers), black indicates a section of course that was/will be used for the 2018, 2019, and 2021 editions, green indicates a section that is used in 2021 and was not used in 2018 and/or 2019, and red indicates a section that was used in 2018 and/or 2019 and will not be used in 2021. All map layers are enabled at the start and may be hidden using the toggles in the upper right of the screen. The base map can be changed in the upper right as well. Right click drag to pan, mouse wheel roll to zoom, and right click on a feature to display an information popup. While most of the map functionalities will work using a touch screen, they are optimized for computer setup with a mouse or similar device. Course maps for 2021 are from publicly available .gpx files provided by the race organization and course maps for 2018 and 2019 are from participants. Elevation calculations are made using a 1 arcsecond DEM (about 25 meters). This map was created very quickly in the Lower Peninsula by a person who is only vaguely familiar with the trail systems involved and who not affiliated with the race organization in any official capacity. Please use accordingly.

Comparison between 2019 and 2021 courses for The Iceman Challenge, a mountain bike race in Michigan's Lower Peninsula. 2019 route is from the .gpx track created by one of the participants; 2021 route is from the race's website: https://ridewithgps.com/routes/36060572

How far away are the trails? This is an interactive map of some "nearby" places to ride trail bikes (relative to my LBS, Motorless Motion). Some are purpose-build MTB trails, others are public, natural-surface trails where mountain bikes are allowed. This is a work in progress and is (obviously) not an exhaustive list.

A (sometimes) monthly analysis of Isabella County Strava (cycling) segments. Part of my ongoing series "Overanalyzing Unimportant Things."

Map of the largest known individual(s) for 63 species in located within Isabella County in the central lower peninsula of Michigan (USA). This map is a continuation of a project originally completed in 1999 by Hud Keenan and 24 of the trees from his list are still the largest known individuals in the county (shown in green). For 31 trees, new largest individuals have been identified (shown in blue) and 20 additional species have been added to the list, 13 of which are shown in purple. For additional context and discussion, see rpubs.com/fecr2o4/btPlots . Last updated November 20, 2020.

A Voronoi map partitions an area (in this case, Michigan) into sub-regions based on geometric proximity to a given set of points (in this case, active beer breweries). I compiled the list from the Brewers Association membership directories and the Michigan Brewers Guild membership list with a few additions from the Brewsader app (Grand Rapids area) and my friend’s Untapped history. I would like to call it “All of the breweries in Michigan” but I am sure that there are a few that are missing and it does not include 6 breweries that are described as being temporarily closed on Google Maps (on 8/31/2020).

Last updated August 19, 2020.
