Welcome to the Third Annual Monster Mash 5k. On Your Left Fitness partners with the Town of Oro Valley Parks and Recreation and Steam Pump Ranch in hosting the Monster Mash Party and 5k Run/Walk. In addition, there will be a KIDS' FREE FUN RUN, where kids can come run in their halloween costume. 

New in 2018 - This is NOT just another 5k. You will have to perform tasks at six stations on the course before you run out to the turn around on the riverpath. There will be one final station before you cross the finish line.

Please read the following so you understand how the race will unfold:

The Course

It will be a chip start/chip finish. The race starts in Steam Pump Ranch, runs through the hayride field before you enter the riverpath to the turnaround in the Oro Valley Marketplace. Runners will start in waves of 10-15 participants with a chip start to chip finish time. You are free to start running between 6:00 p.m. and 6:30 p.m. No one will be allowed to start after 6:30 p.m.

Station One - Pumpkin- Grab an orange balloon and blow it up. Draw a face on it.  Run to Station Two

Station Two- Smashing Pumpkins- Smash the orange ballon (your pumpkin) by sitting on it. Run to Station Three

Station Three - Monster Meal - Eat a DONUT on a string without using your hands. Run to Station Four

Station Four - Witches Brew - Wash down that donut down with a cup of root beer (or water). Run to Station Five

Station Five - Monster Limbo - Walk under a bar. Run to Station Six

Station Six - It's a Hay-Of-A-Time -  Scale the hale bales and then run out onto the Rirverpath to the turn around. 

Station Seven - Riddle Me This? - Just before the Finish Line will be a table with pieces of paper. You will grab a piece of paper and read the riddle. When you think you know the answer to your riddle, then you will run across the finish line (timing mat). You will be asked to see your riddle. If you correctly answer the riddle, your chip time stands. If you have the incorrect answer, you can do 10 burpees to keep your time, or we can deduct one minute off your time. 

Participants who register by August 31, 2018, are guaranteed to receive an event-specific t-shirt.  ALL 5k participants will receive a custom finisher's medal and a free BBQ dinner. 

The kids will enjoy a free fun run through the hayride field and then back to the finish line. Each child will receive a bib number and finisher's medal. The finish line area includes a maze, pumpkin painting, bobbing for apples, Spook Alley, and Zombie Archery Shoot, courtesy of Oro Valley Parks and Recreation/Steam Pump Ranch. 


1st, 2nd and 3rd Place Overall Male and Female Awards.
