Press Release - Grandma's Marathon - 3/1/21

FOR IMMEDIATE RELEASE

  Grandma's Marathon Utilizes Crowd Science Expert In Planning 2021 Event

     Leading Expert Marcel Altenburg Helping to Analyze 2021 Race Plan

(DULUTH, MINN.) --- Grandma's Marathon-Duluth, Inc. has partnered with 
world-renowned crowd scientist Marcel Altenburg of Manchester Metropolitan 
University to optimize the event's participant flow as part of the 
organization's COVID-modified race plan.

Altenburg has previously worked with larger marathons like London, Berlin, 
Chicago, and New York as well as other major marathons around the world. He 
has developed crowd science software called Start Right, which uses a 
unique mathematical algorithm to help race organizers visualize, predict, 
and control the flow of participants throughout the entire race.

"Grandma's Marathon is unique in its setup and all measurements of the 
event are very fortunate," Altenburg said. "With the right adjustments, 
this race can be organized with social distance in the place at the start, 
through the course, and at the finish."

Grandma's Marathon is planning a half capacity event, including but not 
limited to the following changes on race day:

- Bus Transportation – Buses to the start line for the marathon and half 
marathon will allow a maximum of 25 participants, and all public transit 
safety guidelines will be in place. Participants will exit buses in a 
controlled fashion to ensure there is always adequate space in the start 
corral.

- Rolling Start Line – Participants will enter a start corral for both the 
marathon and half marathon, which will be spaced to allow for appropriate 
social distancing. Once in the corral, participants will immediately 
advance toward the start line. Participants will then be released from 
separated lanes in staggered fashion, five at a time, to control the flow 
onto the racecourse.

- Masks & Face Coverings – All participants, volunteers, staff, and others 
present will be required to wear a mask or face covering at all times other 
than while actively participating in a race. This includes but is not 
limited to on the bus, in the start corral, and after crossing the finish 
line.

Altenburg's analysis of the current plan, with the above safety measures 
included, shows a decreased density that allows for a minimum of 12 or more 
feet of spacing between participants at all times during the race. In 
general, participants will have 20 feet of possible distance to other 
people at most points on the racecourse.

"Start Right is an amazing tool that is helping us plan an effective race 
weekend with confidence," Grandma's Marathon Race Director Greg Haapala 
said. "With this analysis, we know our racecourse and the established 
capacity limits allow for the appropriate spacing between participants, but 
we will still require everyone involved to act responsibly throughout the 
event."

Altenburg's model checks the participant density and spacing at all points 
along the racecourse, including the start and finish lines, aid stations, 
or narrow sections of roadway. At one of the highest density spots, the 
finish line, his analysis shows the 2021 plan decreases the peak by 64 
percent from 2019.

"We measured the entire course and simulated every participant based on the 
specific data of the event," Altenburg concluded. "The result is that 
Grandma's Marathon is uniquely equipped to be among the first marathons to 
come back when the time is right."

Marathon weekend, which is scheduled for June 17-19, 2021. There is also a 
video simulation available on our YouTube channel, linked here ---

Altenburg has also done crowd science analysis for professional soccer 
teams, stadiums with up to 100,000-seat capacity, airports, and more than 
100 other races around the world. His work has been featured in 
publications like the New York Times, Washington Post, and Runner's World.

He has a Master of Arts in Human Science from Helmut Schmidt University and 
a Master of Science in Crowd Safety and Risk Analysis from Manchester 
Metropolitan University.

ABOUT GRANDMA'S MARATHON

Grandma's Marathon began in 1977 when a group of local runners planned a 
scenic road race from Two Harbors to Duluth, Minnesota. There were just 150 
participants that year, but organizers knew they had discovered something 
special. Grandma's Marathon weekend draws approximately 20,000 participants 
for its three-race event each June.

The race got its name from the Duluth-based group of famous Grandma's 
Restaurants, the first major sponsor of the Marathon. Over time, the level 
of sponsorship with the restaurants changed, but the name stayed the same. 
Grandma's Marathon-Duluth, Inc. is a 501(c)(3) tax-exempt nonprofit 
organization with a 17-member Board of Directors and a small, nine-person 
staff.
