What is the 100 Mile Endurance Challenge?

Who is putting on the 100EC?

Run-Walk Events is the organizer of this event.

What is the 100 Mile Club®?

The 100 Mile Club® the benefiting organization for the 100EC. It is a national, school-based program with the goal to run or walk 100 miles during a school year. The program also teaches kids life skills, goal setting, and self-esteem while making physical activity a healthier habit for life. 100% of the proceeds from the 100EC event will directly sponsor students and program implementation in new and currently participating schools. Those kids who join accept the goal of running (or walking) 100 miles at school during a single school year. It now has members in over 700 schools in nearly every US State as well as three other countries – Canada, New Zealand and Japan! More information about the 100 Mile Club® can be found at http://www.100mileclub.com.

What's the course?

The route for the EC50 starts at the same location as the 100-mile option. It cuts through the heart and hugs the coast of Southern California. Athletes who participate in this event will run through three counties and 10 cities.  Check out the course resources for more information.

What do I need to know before I sign up?

What is the registration cost?

Distance Registration Cost Dates
50 Miles
OPEN Registration  $60.00 12/16/2014 – 7/31/2015
LATE Registration  $70.00 8/1/2015 – 10/5/2015

What is the fundraising commitment?

All runners must raise at least $100 (in addition to registration).  Very few runners have trouble raising this amount. Creating a fundraising page takes just a few minutes. All proceeds of this event go to the 100 Mile Club®.

What are the crew requirements?

None. However, fielding pacers and crew members with a car will increase your chances of finishing and likely improve your time. Note that you will need to provide your own transportation from the finish line.

Can I have dropbags?

Yes. Dropbags must be marked with your bib number and the station; 25 or 50. If you wish to leave anything at the 12.5 or 37.5 mile sub-stations, prior arrangements must be made. Contact us to discuss. Please, do not leave large or valuable items. We take no responsibility for items left at the check-in stations. Clothes will be donated to charity. The rest will be thrown away. Please plan accordingly. Note: It will likely get dark between mile 37.5 and 50. Either bring a headlamp from the beginning or leave one in a dropbag at 25 or 37.5 miles.

What is the cutoff?

The cut off is 14 hours. There are (very reasonable) cutoffs at each of the check-in stations.  (See rules section below.)

What are the awards?

All runners will receive a custom tech tee and a bag with some goodies inside.

Fundraising Awards
The 100 Mile Club® is offering a 100 Mile Club® quilt to the fundraiser who raises the most money. The quilt has been handmade by Dot Lubin! This is a one-of-a-kind quilt and is a coveted prize!

Athletic Awards
Awards will be presented to the following participants:

  • Fastest male & fastest female finisher will receive a special award.
  • All finishers will receive a finisher’s medal.

What is the actual distance?

51.5 Miles

What do I need to know after I sign up?

Create a fundraising page

Runners can create a fundraising page here. The process takes just a few minutes. Next, post the link to your page on your social networks or send it to your friends and family in a personalized email.

Learn the course

Running 50 miles in an urban environment is difficult.  We will mark the course. But, this is not enough. Runners must do their part before the race by learning the course. We recommend that runners run the course (25 miles at a week over two weeks). Another option for those of you out of state is to simply bring up the map on your computer and memorize the street names.  Check out the course resources for more information.

Attend the runner/crew safety briefing on Friday

Please attend the runner/crew meeting held the night before the event. The location is the 100 Mile Club® Headquarters: 2191 Fifth Street, Suite 211, Norco, CA 92860. Check-in will be from 4:00 pm to 7:00 pm. Bring at least one KEY crew member to this meeting. Please, no more than total of three crew with each runner.

Consider staying the night in a local hotel

If you live more than 30 miles from the start line, we recommend that you stay in a local hotel. We recommend the Fairfield Inn & Suites Riverside Corona/Norco as it is within walking distance from the start. Make sure to use the group code END to make reservations. You can also call them directly at 951-340-4500.
