2015 Commuter Cycling Century Challenge - forum

Welcome to the 2015 Commuter Cycling Century Challenge, now in our tenth year.

The Commuter Cycling Century Challenge has a simple goal:
Each member attempts to ride to and from work or school on at least 100 days in the calendar year.
That's just twice a week for four-season riders, three times a week for three-season riders.

We also recognize PCWs-Perfect Commuting Weeks (commuting every single workday), PCMs-Perfect Commuting Months, and a PCY-Perfect Commuting Year.

Current standings

How to join and report your progress

Simply report your commutes by posting in this thread. This thread does not connect to or pull data from your ride log. You have to tell us here.

Your Ride Leader this year (until I get fired for repeated screw-ups,)is Sealion. My role is that of Recording Secretary, not Scorekeeper. You keep your own scores (rides, PCWs, PCMs, PCY, etc). I simply record them in the Standings Table.

Please put all your update info (ride number, milestone dates, PCWs, PCMs, PCY, and distance changes, etc) in the first line of your post. That makes it easier for me to find quickly.

Update as often or as infrequently as you like. We like hearing about everyone else's daily ride and keeping up-to-date. If you want to update only every now-and-again, that's fine too, but we miss you between reports.

Challenge Rules

The rules been mutually agreed upon over the lifespan of this challenge. They provide some degree of confidence that we are all comparing apples to apples. They are not hard-and-fast. We make changes by general consensus when necessary.
  1. Each round-trip commute counts as one (1) commuting-day.
  2. Each one-way commute counts as one-half (˝) commuting-day.
  3. Limit of one commuting-day per calendar day. Remember, we count days, not rides.
  4. Multi-modal commuting is perfectly fine, as long as there's a bike ride in there somewhere.
  5. Substitutions: Students may substitute school for work. Volunteers and retirees may substitute their volunteer location for work.
If you ordinarily update from work, there's no need to report only a half-day if you expect to also ride home. Report the whole day. If the fates intervene, we'll deal with it later.

Accounting and verification

We operate on the honor system. I make no attempt to verify or check the accuracy of anyone's postings. Remember, I'm the Recording Secretary, not the Scorekeeper. Obvious math errors, such as 10 commuting-days in a week or other obvious discrepancies, may prompt a request for clarification.


Verb (intr) to travel some distance regularly between one's home and one's place of work — commute. Collins English Dictionary — Complete & Unabridged 10th Edition.
Most Direct And Safe—The Most Direct And Safe ROUND-TRIP distance between your home and workplace. This is not necessarily the shortest possible trip, but the shortest safe trip.
Perfect Commuting Week/Month/Year—Commuted by bike every day that you went to work during the period. By definition, you can't do any better than this.


A PCW, PCM, or PCY string is NOT broken if on a given day a rider does not ride to work for any of the following reasons:
  • Working at home.
  • Working out-of-town on assignment.
  • Jury Duty


This challenge was started by Anquetil63 in 2006, and was maintained by GTDBike from 2007–2010. Annual CCCC threads also include: 2011, 2012, 2013, 2014

nice work Bruce with the stats and your final ride dropping that ebike.

My own 3394 bike miles in 2015 were 84% for transportation but only 61% for commutes if all had been just MDAS roundtrips.
