Shun the Sun Foundation, a 501(c)(3) non-profit organization, raises money to build shade structures and educate the community on skin cancer awareness and prevention.

The Gilbert Marathon is a dream built by the founder of the Shun the Sun Foundation, Dr. Gregory S. Allen. All of the proceeds from the Gilbert Half Marathon events are donated to Shun the Sun Foundation in order to build shade structures. We work with the Town of Gilbert to bring runners an amazing race through the heart of Gilbert that finishes alongside the Gilbert Days Parade!


Yvette Rangel, Race Director

Hello and welcome to the Queen Creek 5 Races! I am so excited to be a part of bringing this racing event to the Valley! I have run over 100 races from marathons to ultras to 10 and 5ks in the U.S. and abroad. Running has brought so many positive things to my life: clarity, balance, self-confidence, travel, getting to see parts of a city/country I wouldn’t see otherwise, and meeting people from around the world  to name a few.

My goal is to take all my experience running and make this an awesome race that will bring you that same positive feeling! Come out, run, walk, cheer or volunteer, all for a great cause - skin cancer prevention! Partnering with the Queen Creek Spring Festival makes this an even greater event. And remember, “No matter how bad you feel, you never feel worse after running!”

Dr. Gregory S. Allen, Founder of Shun the Sun

Dr. Allen knew from a very young age he wanted to be a doctor. After dedicating two years to go on an LDS mission, and short stint to play college football, Dr. Allen reconnected with his calling to practice medicine.

After several years of working with Deseret Family Medicine, Dr. Allen decided to open his own family practice, and Allen Family Medicine was opened for business in April 2012. Allen Family Medicine is a successful comprehensive care facility located in Mesa, Arizona. Dr. Allen’s primary focus is to effectively communicate with his patients to provide exceptional care. He is dedicated to saving lives and encouraging wellness

Dr Allen is also the founder of Shun the Sun Skin Cancer Foundation a 501(c)(3) non-profit organization. His passion is to educate children and families on proper sun protection and skin cancer awareness.

He is also the Medical Director of Deseret Aesthetic & Lifestyle Institute which is a full-service medical spa facility adjacent to Allen Family Medicine.

Dr. Allen has a beautiful wife, Tera, and five children who also share in his passion for the Shun The Sun Foundation.
