Welcome to the 2019 100 Miles in 100 Days Challenge!

This year, we are asking all participants to register for the Challenge so we know roughly how many individuals are participating. We would also like to know a little about you, primarily how you would like to communicate with us throughout the Challenge. Since this is a self-guided program, we know it is easy to lose motivation around the holidays, and we want to make sure you're successful with your Challenge. So, if that requires a friendly note or two throughout the holiday season from us to get you back on track, we're in!

We've also included the program guidelines at the bottom of this email for those of you who are new to the Challenge. So, let's get the 2019 season started!

Welcome to the 2020 100 Miles in 100 Days Challenge! The program begins at 8 a.m. on Thursday, November 1, 2019, and closes at 4 p.m. on Friday, February 8, 2020. Below are the guidelines for the program:

The program was initially developed for hikers. Over the years, the department has expanded the program to include all user groups. This change required mileage adjustments to keep the program consistent and fair for all participants. Below is the mileage breakdown for the various user groups:
  • Hikers: 100 miles
  • Trail Runners: 100 miles
  • Mountain Bikers: 200 miles
  • Horseback Riders: 200 miles
  • Combo: You may combine options; however, 75 percent of your challenge must be completed via your primary mode and 25 percent via secondary mode. For example, if you decide your primary mode is trail running (100 miles) and mountain biking (200 miles) is your secondary mode, you must run 75 miles, and the remaining 50 miles must be completed on your mountain bike for a total of 125 miles.
REGISTRATION: ALL participants are required to complete a short registration form. This will help us to communicate with you throughout the program.

  • Participants must visit a minimum of three Maricopa County parks or two Maricopa County parks and the Maricopa Trail/Sun Circle Trail.
  • We understand that participants have their favorite trails in city and state parks; however, this program is managed and paid for using Maricopa County Parks and Recreation Department funding. If you would like to trek in a park managed by another agency, we encourage you to continue doing so; however, we are unable to count that mileage towards Maricopa County’s 100 Miles in 100 Days Challenge.
  • The participant may NOT combine their logs/miles with another participant's log/miles to reach the 100 or 200-mile goal.
LOGS: All participants must log and report their miles throughout the Challenge. There are two types of logs used for the Challenge:
  • Hard copy: There are several different hard copy logs available on the website for use. Those using the hard copy logs must have a staff representative sign off on miles trekked. We understand that park representatives aren’t always available when participants are recreation; however, participants must receive signatures at least once a week.
  • Those using hard copy logs must submit their final log electronically to 100MileChallenge@mail.maricopa.gov. If you do not have a scanner, you may ask a staff member in a nature center to scan/send the document in for you.
  • All program logs must be submitted/received by 4 pm on Saturday, February 8, 2020, to meet Challenge requirements – no exceptions. 
  • Electronic: If you plan on using the electronic option, you will need to select a mobile app. of your choice to track your miles. Once your trek has been completed, you will complete the Electronic Log Submission Form. Mileage and park information will be transferred by staff into a group Google spreadsheet housed at https://bit.ly/2x4SfiK. If you are using this option, you do NOT need to submit your log at the end of the program since we have tracked your progress throughout the Challenge.
  • All celebrations will be hosted on Saturday, March 7, 2020. Please check the events calendar for times as times may vary from park to park.
  • All participants who complete the 100 Miles in 100 Days challenge will receive a limited edition tee-shirt at the park program finale celebration on Saturday, March 7, 2020*.
  • In order to receive your shirt, you must complete the Tee-shirt Order Form. Shirt order forms must be submitted by 4 p.m. on Friday, February 8, 2020, to help us meet our timeline with the vendor. Please do NOT submit your form prior to finishing your miles. 
  • Tee-shirts must be picked up at the park. Participants may make arrangements to pick up a shirt from the park at a later date. You may also send a family member/friend to pick up your shirt.
  • Tee-shirts will NOT be shipped to customers and park(s) will not be responsible for product not picked up after Sunday, March 31, 2020.
  • Participants may receive no more than one tee-shirt per campaign year, regardless of the number of miles hiked, biked, ridden or ran.
  • Pets may join participants on hikes; however, participants MUST be human to be eligible to receive a tee-shirt and qualify for the grand prize drawing.
  • To be eligible for the grand prize drawing of an Annual Pass ($85 value) and $25 Nature Center retail voucher (total value not to exceed $110).
  •  If the selected winner currently holds an Annual Pass, the Annual Pass will be renewed for one year upon date of expiration.
