2015 Taillight Rules

posted Jun 11, 2014, 8:03 AM by Pete Steve   [ updated Dec 7, 2014, 4:28 PM ]

Because of the configuration of our night loop, a single blinking taillight could become  a hazard.

We require at least one constant-burning taillight, affixed to the bicycle.

An additional blinking taillight, affixed to the bicycle or to your person,  is allowed.

Rapid Wheelmen Training Rides

posted Mar 21, 2014, 8:45 AM by Pete Steve   [ updated Oct 24, 2015, 8:05 AM by Richard Weis ]

Our friends in the Rapid Wheelmen bike club arrange a series of spring rides ideally suited for N24HC training.

April 30, 2016:  Dawn Patrol Special Edition - Dawn Patrol is a weekly ride (typically 45 - 65 miles.)  On April 30th, Dawn Patrol Special Edition will ride Loop 1 of the N24HC route.   In addition to being a training ride, this is also a chance to become familiar with the N24HC route.  The ride will start at 7:00am from Thornapple Kellogg Middle School.   The ride is free, but there will be a stop for lunch in Delton.

May 14, 2016:  Ride Around Kent County - This ride will begin at 7:00am SHARP at Johnson Park in Grandville, and will hit all four corners of Kent County.  Riders that complete the entire loop will ride 145 miles.   Full SAG support, lunch, snacks, and drinks are provided for a $15 entry fee.

June 4, 2016:  The 100 Grand - The 100 Grand offers a 141 mile option.   Riders start between 6:45am and 7:00am to complete the 35 mile route before riding the 105 mile route.   Full SAG support, rest stops, and a lunch stop (with live music!) are provided for a $30 entry fee.

If you are within driving range of Grand Rapids, consider these great training opportunities.

Proposed Change in Place Calculation

N24HC Riders:

The N24HC is contemplating a change to how places are assigned that will bring us more into line with the rest of the sporting world.

In a short, one sentence summary, under the proposed change everyone's position would be 1 + the number of riders that rode more miles (the highest mileage rider is 1st place, with zero riders that rode more miles.)

Currently, if there is a tie, the N24HC doesn't "skip a place." For example, if there is a tie for first place, the N24HC currently awards two first places, a 2nd place, and a 3rd place. Under the new system, we would award two first places and a third (in line with what the rest of the sporting world does.)

Where this really makes a difference is deeper in the field. In the last N24HC that I rode (2012), I rode 302.8 miles. There were 78 riders that rode more miles than I did, but because of the way that the N24HC handles ties, I was officially listed in 38th place. Even within my category, there were 13 riders that rode more miles than I did, but I was still awarded 11th place in my category.

For myself, since I manage the server were the database is kept, I'm able to look at the raw numbers and see how I actually did compared to the rest of the field (79th out of 311, if you care ), but no one else is in a position to do this, so it is difficult or impossible for anyone else to really determine how they did compared to the rest of the field or the rest of their category.

Before implementing this change, the N24HC would like feedback from as many riders as possible. Do you agree that this change will make it easier for riders to know how they really did? Is the change worth the (hopefully small) amount of confusion it might cause (mostly in comparing your rank in events pre- and post- change)?
