The Tim’s Run/Walk has decided to postpone this year’s Run in September due to a recent opportunity that was presented to the organization. We will be working hard to make next year’s race as wonderful as the past years, and better, with more growth in raising funds towards our mission. We thank you for your continued support, and sincerely look forward to you joining us next September.

For this year, If desired, donations can still be made to the Timothy J. Flaherty Myelofibrosis Fund PO Box 1171, Yarmouth, ME 04096. Many thanks again.

Thank you for visiting the Tim’s Run website. Tim’s Run is a 5K Run / Walk in memory of Timothy J. Flaherty. Tim was a true family man. A loving husband, father, grandfather,best buddy, vegetable gardener, outdoorsman, and a career man with an impressive 33-year career as a Portland Firefighter… and a runner. Tim passed away August 30, 2011 at only 63 years old following a courageous fight against Myelofibrosis, a rare blood cancer that is now being linked, among other particular cancers, to firefighters. Although we all lost Tim on this day, we feel like we have never lost his spirit.

Since then, we have formed The Timothy J. Flaherty Myelofibrosis Fund, and have committed to hosting an annual blood drive in December, and this annual race, to raise funding, support, and awareness for people who are effected with this illness and other related diseases. Tim’s family along with friends have joined together to honor Tim’s memory with a run through his hometown of Yarmouth, Maine.

We have had tremendous support each year that has been filled with such great energy and community vibe and we have continued to surpass our fundraising goals yearly for each of our beneficiary foundations!! The funds raised through Tim’s Run are donated to The MPN Research Foundation which is focused on research, support and awareness to Myelofibrosis and other blood cancers, and the Maine Cancer Foundation which is dedicated to helping Maine citizens battling cancer through the direct support of various organizations throughout the State including research, treatment and patient care. We encourage you to visit their websites for more information about these tremendous organizations. Please visit: www.mpnresearchfoundation.org and www.mainecancer.org

As we approach this years’ race, we are looking to surpass our goal once again and truly hope you will join us! We truly thank you and look forward to a day of family, old friends, new friends and a day to remember Tim and others who have battled cancer, and those that are still fighting.

All proceeds benefit the Timothy J Flaherty Myelofibrosis Fund, the MPN Research Foundation and the Maine Cancer Foundation.
