One week until my new book releases!!


I'm super thrilled to announce that we are just one week away from the release of my new book The 365-day Running Journal. I can't wait for you to get it in your hands so that you can start logging your workouts while staying motivated with lots of inspiring quotes and tips. 

I'd like to extend a huge thank you to the following professionals who reviewed my book.

"The 365-Day Running Journal is flawlessly designed to encourage an individual to document their running journey. The uniqueness of this journal is the expert advice provided by author Marni Sumbal who is a nationally recognized sports dietitian, coach, and athlete herself. Marni provides the reader with helpful tips each week followed by a section to comprehensively document details of the workout. Throughout the journal Marni gives advice on how to develop a training plan, provides up-to-date nutritional guidance, and tips to prevent against injury. The weekly and monthly tips found throughout the journal are essential in keeping the runner motivated while setting a positive trajectory for long-term success in training, health, and happiness in sport."―Caitlin Glenn Sapp, PT, DPT, owner of Crew Racing and Rehab

"Marni has done an exceptional job at creating so much more than a training journal. The key quick tips, inspiring quotes, and specific running focused information makes it easy to stay motivated, properly fueled, and injury free while seeing the miles add up! This journal can help any runner turn the 'run happy' dream into a reality!"―Kim Schwabenbauer, MS, RD, CSSD, NASM-CPT, USA triathlon coach and founder of Fuel Your Passion, LLC

"Marni’s passion for running well is contagious. In The 365-Day Running Journal, Marni has written a wonderful book that runners of all abilities will appreciate. The journal creates a place for runners to reflect on their training, nutrition, and how they feel each day and week to safely progress their running for their individualized needs. Marni’s pro tips and motivational quotes are just the thing to help foster consistency for excellent runs."Scott Kaylor, PT, DPT, SCS

"For most, if not all runners, consistency of training and longevity reign supreme. To this end, developing rock-solid habits, executing workouts, and keeping tabs on your progress is essential. To accomplish this one needs a simple, practical resource that also reminds athletes of their successes along the way. Unsurprisingly, Marni Sumbal delivers that and much more. If you are looking for a no-nonsense approach for yourself or friends, who enjoy running, this is long overdue resource. Enjoy!" Chris Johnson, MPT, MCMT, ITCA, Zeren PT & Performance - Owner and Director
