Course Note

The Emerald City Half & Quarter Marathon is open and fully supported three hours, 45 minutes. However, for safety reasons, Half Marathon participants who have not reached the 5.5-mile mark (corner of McKitrick and Hyland Croy roads) by 8:30am (15:00 per mile pace) will be diverted to a 10-mile course. The 10-mile route is on the original course but does not include the 3.1-mile loop through Glacier Ridge. Ten-mile finishers will receive the same Official Finisher’s Medal.

Fleet Feet Sports / Marathoner In Training Pacers

Why use pacers?

Pacers are at the starting line with a focus on the needs of the runners in their group. First, the pressure of calculating the pace is removed — the pacer will keep a steady pace that takes stress off the runner — no starting off too fast. Advice and encouragement are the benefits to running with the pacers. Pacers are experienced runners (many are coaches) who want to give back to the running community — it is a voluntary position so they are here to share their love for the sport and help the runner achieve their goals. Pacers will help keep the runner motivated through conversation, stories, and/or sage advice. Lastly, it is fun to run with a group and meet others who share your goals! Pacers will be provided for the following times:

Half Marathon Finishing Time h:mm (pace)

  • 1:45 (8:00 min/mile)
  • 1:50 (8:25 min/mile)
  • 2:00 (9:10 min/mile)
  • 2:10 (9:56 min/mile)
  • 2:20 (10:41 min/mile)
  • 2:30 (11:27 min/mile)
  • 2:40 (12:13 min/mile)

Quarter Marathon Finishing Time h:mm (pace)

  • 1:00 (9:10 min/mile)
  • 1:05 (9:56 min/mile)
  • 1:10 (10:41 min/mile)
  • 1:15 (11:27 min/mile)
  • 1:20 (12:13 min/mile)
  • 1:25 (12:59 min/mile)
  • 1:30 (13:45 min/mile)
  • 1:40 (15:16 min/mile)

Which pace group?

A pacer cannot offer miracles — it is dependent on the runner's training. When choosing a pace group, consider your training pace — your longest run each week is usually run a minute to a minute and a half slower per mile than your race pace. Use a pace calculator and figure out what your race pace should be — then choose a group accordingly. During the race you can move to a slower/faster group depending upon your needs.

Where to find the pacers on race morning?

The Pace Leaders will assemble in the start corral and will be holding their pace sign with the expected finish time and will be wearing pacing shirts. At 15 minutes before the race they will let runners know how they will handle water stops — this is the time that runners can ask last minute questions.

Weather forecasts will be monitored prior to the event paying special attention to the possibility of heavy rain, thunder and lightning, high winds and extreme temperatures. If necessary, athletes will be made aware of these predictions on this website (www.emeraldcityhalfmarathon.com) so that participants can properly prepare for severe weather during the race as well as possible course alterations. Severe weather updates will also be sent to participants via email as necessary.

The Race Director and Medical Director will monitor the weather and make a decision if any action will be taken to modify the race. Possible changes include: altering the start time for the race or in extreme situations, cancellation of the event. Please listen closely to all public address announcements at the starting line of the race.

Visible lightning will cause the race to be postponed for a minimum of 15 minutes. Additional sightings will continue to delay the race in 15 minute increments.

If heat is predicted, extra water will be provided to the athletes, both prior to, during and after the event. The medical team will be alerted that athletes may require additional medical attention during and after the event due to the high temperatures. If it is felt that it is unsafe for participants to start the race due to severe heat that race may be cancelled.

Race personnel reserve the right to delay, cancel, or suspend the race due to inclement weather. Participants must abandon the race if ordered to do so the race personnel, medical staff, fire or police officers.

Flag Warning System

We have devised a flag warning system to communicate race conditions to participants on the course. Look for the color of the flag at each re-fueling station.
