This loop starts in Ankeny Iowa and is a continuous bike trail loop going through Ankeny, Johnston, Grimes, Waukee, Dallas Center, Minburn, Perry, Bouton, Woodward, Madrid, Slater, and Sheldahl utilizing paved bike paths through each community with most of the route consisting of the very well known High Trestle Trail and Raccoon River Valley Trail.
You’ll be in the middle of the country for most of the route, however, the large amount of communities passed through make this a solid option for an unsupported, self supported, or supported attempt.
With a low amount of vert for the mileage this should be a great challenge for many through the years.
