The winters first big long race is back for its 45th year.  Things will look a little different but you can expect the same amazing race day experience for those who chose to register for the live event.  

Due to Covid 19 requirements and race capacity limits, this years live event will be limited to the 10 mile distance only and a max of 500 total participants divided between 2 heats.  Virtual runners will have the option of 5, 10, 15 or 20 miles.  Virtual participants will have until March 31st to complete their event.

The Spring Thaw starts and finish's at North Parks iconic boathouse as we run counterclockwise loops around the lake.

As per Allegheny County, we are allowed to have 250 participants per wave at this years event.   Additionally, we need to keep everyone spaced out as best we can prior to, during and after the race.   As a result, we will be following the details set forth below.

  • The live race will run in 2 heats and each heat will be run in waves starting every few minutes to keep participants socially distanced and safe.  
  • The first heat will go off at 8:00 am and the second heat will begin at 10:30 am.  
  • Runners will be assigned their heat based on their predicted finish time which is a required question during registration.  
    • Based on the 2020 Spring Thaw Results, 1:35 - 1:40 finish time would be the approximate split between heat one and heat two.   This is subject to change based on this years participants.
  • Runners will receive their official heat in an email with race instructions the week prior to the race.  

HEAT 1 - 8:00 AM START

  • Runners will be sent off in groups of no more than 50, divided by pace, and socially distanced.
  • Runners will line up next to cones in the coral area prior to each wave.  Comes will be set socially distant apart.
  • Runners will waterfall start under the direction of the timing director.  Please listen for announcements. 
  • There will be approximately 90 seconds between waves.
  • You may remove your mask once you cross the start line if you are able to maintain a 6 foot social distance from fellow competitors.

HEAT 2 - 10:30 AM START


There will not be an on site awards ceremony after the race but all overall and age group results will be listed on the Athlinks results page, our GCXC PA results page and also posted on our Facebook page after the race.
