The annual Almgren "Mayday" Race will not be held in 2021, due to the
global pandemic. It was also not held in 2020.
Hopefully, the 45th race will be held on May 8, 2022.
Almgren "Mayday" Race was held in the rain on Sunday May 5, 2019.
The 2019 winners: Princeton Math
Here are the detailed 2019 Race statistics and the recent history of the race.
Here is the link to for a general description of the race and its history. You can also find a leg-by-leg breakdown of the course, and driving instructions with a Google Map of the course in even years.
In odd years, the race starts in New Brunswick (at the Landing Lane bridge) and ends in Princeton (at Alexander Road since 2001). In even years, it starts in Princeton (at Washington Road) and ends in New Brunswick. The race has almost always been held on the first Sunday of May, starting at 10:00 AM.
|In 2018, the 44th race was won by the Rutgers Math team, with a time of 2:53. There were 7 teams competing, including Rutgers, Princeton and Columbia Math. It was a very close race that year, with many lead changes between the top 3 teams. The runners in leg 2 had to climb over a downed tree, and geese chased runners in leg 7.||
The winners: Rutgers Math
|In 2017, the race was won by the Princeton Math Team, with a time of 3:01. There were 7, 8 or 9 teams in the race, depending on your definition of team. One team disappeared near Griggstown, and went to lunch. A bystander spontaaneously ran leg 4 for a Physics team in boots. To round out the fun, the Princeton Math A and B teams shared the first and last runner, creating a virtual gap of 22 minutes.||
The winners: Princeton Math
|In 2016, the 42nd race was won by the Rutgers Physics teams, with a time of 2:52. There were 9 or 10 teams competing. This was the first race held in the rain since 2009, and a few runners were chased by geese. A one-person "team" formed spontaneously at 10-mile locks, and completed the last 8 miles to the surprise of the timers.||
The winners: Rutgers Physics (speedy, classical and party teams)
In 2015, the 40th race was won by
the Rutgers Math and Rutgers Physics teams, who tied.
The winning teams crossed the finish line in a time of 3:03:40,
hand in hand.
There were 9 teams, including the Slowly Converging Zombies, who chased Team Morel and ate part of a timer, causing a loss of data.
Tied for the victory: Rutgers Math and Rutgers Physics
The race was just a few days after a major storm (see photo); parts of leg 2 were badly damaged, and leg 6 was rerouted through South Bound Brook. In addition, Rutgers Math started running at the wrong location (Alexander Road) and crossed the starting line (Washington Road) over 11 minutes after everyone else.
|In 2013, the Rutgers Mathematics team won the 38th Fred Almgren Memorial "Mayday" trophy, with a time of 2:58. There were 9 teams competing, and the Princeton Math team took second place.|
|In 2012, the Princeton Economics team won the 37th annual Fred Almgren memorial race trophy, with a time of 2:43. There were six teams competing, and the Rutgers Math team took third place.|
In 2011, the 3-person Princeton Physics team won
the 36th annual Fred Almgren memorial race trophy, with a time of 2:39.
The Rutgers Math team took second place, and 8 teams competed.
In 2010, the Princeton Running Club won
the 35th annual Fred Almgren memorial race trophy, with a time of 2:37.
The second and third place teams were Princeton Physics (2:54) and
Rutgers Math (2:58), and 11 teams competed.
Teams had syncronization issues this year. The Rutgers Math teams were absent at the start of the race, showing up about 90 seconds later. The Princeton Fun Math runner for leg 6 started 16 minutes before the leg 5 runner arrived. Neither event affected the team standings. In addition, this was the hottest race since 1978 (when several runners suffered heat stroke); fortunately everyone adjusted their pace this year and we had no casualties.
This was the soggiest race in years, due to almost steady rain,
but the towpath was in remarkably good shape. One team's fourth leg
was delayed by 7 minutes, as their designated runner took off in the
wrong direction and had to be replaced.
In addition, the clock timing the end of the race broke before the times could be adjusted, so the final times reflect our consensus best guesses.
The 2008 Almgren "Mayday" Race was held on Sunday May 4, There were 11 teams (second most ever), and the winner was the Rutgers Math Fast Fourier Transform team with a time of 2:48. The race was one of the closest in years, with 5 lead changes overall, and the top three teams finishing within one minute of each other.
The 2007 race was held on Sunday, May 6th, from Rutgers to Princeton. There were fifteen teams competing (a new record), and the winner was the Princeton Computer Science Team with a winning time of 2:47. The race was made especially interesting this year because of the poor condition of the towpath after a recent storm, with runners jumping over trees and skirting washed-out sections in places.
The 2006 race was held on Sunday, May 7th. There were three teams competing, and the winner was the Princeton Psychology Team Green with a winning time of 2:59. (This team was an amalgam of Psychology and Economics graduate students.}
The 2005 race was held on Sunday May 1st from Rutgers to Princeton. There were eight teams, and the winner was the Rutgers Physics team, with a time of 3:00. In addition to the math teams from Rutgers, Princeton and the Institute for Advanced Study, there were two Physics teams, a Computer Science and an Engineering team.
The 2004 race was held on Sunday May 2nd, from Princeton to Rutgers. There were three teams, and the Rutger Math team defended their title, with a time of 3:11 for the 25.1 mile course. This was the slowest winning time in the 29-year history of the race.
On Saturday May 10, 2003, the race went from Rutgers to Princeton.
There were six teams, and the winner was Rutgers Math with a time of 3:07.
In second place was Columbia University, which competed for the first
time since 1979.
In 2003, the race was 25.5 miles. The first leg was shortened by about 0.2 miles, and the second leg was lengthened by 0.15 miles, due to construction blocking the towpath.
On May 5, 2002 the race went from Princeton to Rutgers, ending with a picnic in Johnson Park. There were 8 teams, and the Princeton Physics 'A' team defended their title, with a time of with a time of 2:34 for the 25.1 mile course. The Rutgers Undergraduate team ran the third leg in the wrong direction, and their team time was computed "virtually."
On May 6, 2001, it went from Rutgers to Princeton, ending at Alexander Road,
near the picnic area. There were 9 teams, including two Physics teams
(one from each school). The winner was the Princeton Physics team,
with a time of 2:38 for the 25.7 mile course.
There was also a bicycle team for the first time.
The D&R Canal was completed in 1834, as a fast but safe route between New York and Philadelphia, and was closed for shipping in 1932. The main part of the Canal was 44 miles long until the 1930's. The concrete Mileposts found along the towpath give distances "xx-yy". This refers to the distances (in miles) to the original Trenton end (xx) and to the original New Brunswick end (yy), so that xx+yy=44 miles.
Today, the main part of the canal is only 34 miles long. One end is now at
the Landing Lane bridge in New Brunswick, near the milepost 41-03;
the original New Brunswick terminus of the canal has also been recently
restored, and is about 3 miles away in Boyd Park. Between these points
in New Brunswick, there is about one mile of the canal which was
covered in the late 1970's when the highway, Route 18, was built.
Another mile of canal is also covered by Route One, in Trenton.
The Main D&R Canal, along which the race proceeds, is also used as a source of drinking water by several municipalities, providing about 75 million gallons of drinking water each day. So treat the Canal as a Watershed Area.

1) All markings "No Parking", etc. are according to State Park guidelines.
Several new access points and parking areas have been added since 1976.
2) When the canal was in operation, the towpath had no trees and was muddy.
There are numerous trees, and tree roots are a danger for runners.
Especially on the legs from Bound Brook to East Millstone.
During 1999-2000, almost the entire trail was given a sand topping.
3) The course was re-measured in 2001 and 2002; several inaccuracies
were corrected, including:
Leg 1 changed from 3.8 to 3.66 miles (Milepost 40 appears to be mislocated)
Leg 2 changed from 4.0 to 4.15 miles
Leg 3 changed to 3.33 miles
Distance in legs 6&7 adjusted for different exchange points
