  • There is no “double dipping” between the marathon and the relay. Runners must chose one event or the other.
  • Each relay team member must run only the leg assigned to that runner. Team members must not join the member running the final leg at any time, especially not as they run the stretch to the finish.
  • All teams will have their race day photos and video audited, any team that consists of only one runner running the full marathon distance will be disqualified. The relay is intended for 2-person teams ONLY!

Please visit the CIM Event Rules page for additional information.

Race Number:

All CIM participants must wear an official race number on the front of their body, pinned to their outer layer of clothing. Numbers must be fully visible at all times (not cut, folded or obscured). Runners who run without their bib properly attached and displayed risk not having their finish time and split times recorded and not being listed in the results. At Packet Pick-up each team will receive a timing chip attached to an ankle bracelet which must be passed from runner to runner. Relay runners will be timed by this chip. 

Gear Check:
  • You may bring your warm-pre race clothes to the start of the marathon (or to the start of your relay leg), and it will be transported to the finish for you.
  • Gear bags will be clear. The clear bag you receive at packet pick-up is the only bag acceptable to check on race day into the gear trucks at the start. Other bags will NOT be accepted.
  • Relay Leg 1 & Marathon: To identify your bag, write your bib number with a marker in the colored box printed on the clear bag. Do NOT place anything of value in your bag, especially car keys or cell phones. The SRA is not responsible for lost items. Before the start of the race, hand your bag to a volunteer at the start area bag trucks that will transport your bag to the finish.
  • Relay Leg 2: To identify your bag, write your bib number with a marker in the colored box printed on the clear bag. Do NOT place anything of value in your bag, especially car keys or cell phones. The SRA is not responsible for lost items. Relay participants will be allowed to leave the clear bags on the bus. Those bags will be transported to the finish.
  • DO NOT over fill gear check bags.
  • At the finish line, claim your bag on 10th street, to your right as you exit the CIM controlled zone.
