  This run/ruck is a great way to prepare for your wildland pack test. Due to complexities of verification amongst different fire districts, this event is unable to serve as an official pack test. For those interested in seeing if they are as "Fit as a Firefighter"; To qualify as a wild-land firefighter, you must complete 3 miles in 45 minutes or less while carrying 45lbs (weighted vest or backpack both allowed). This event is free to first responders, but open to the public for $35 entry fee. If you are a first responder, email 1199callingmayday@gmail.com OR use the "Question?" button in the contact section to get a coupon code. Be sure to provide your name, fire agency, and best method for contact.

  People looking to complete a "pack test" practice are responsible for obtaining their pack or vest for the event. Packs and weighted vests can be weight checked during check in the day of the race, if needed for bragging rights. Participants will be started in waves every 30minutes to ensure that traffic jams don't take place and interfere with participant times. If you expect to be one of the faster participants, it is recommended that you be in one of the first heats of the day, 8am-9:30am. If you plan to be slower, or just want to support the cause and have a nice walk around the lake, please plan to come after 10am.

  WARNING: Walking/Jogging/Running with a pack or weighted vest adds a significant amount of impact to bones and joints. If completing this event with a pack or weighted vest, it is important that you have trained with weight to avoid possible injuries. Individuals are responsible for their own wellbeing/safety. The race organizer assumes no responsibility for any injuries sustained during this event.
