Runner of the month — July

Mercedes “Mom” Acosta


She just ran her second marathon at the tender age of 73! We talked with WeRunSF runner Mercedes Acosta, also known as "mom.” She has finished dozens of races and often wins her age group!

When did you start running? Which was your favorite race?

I first started with walking, then running, eleven years ago. My favorite race is the SF Rock ’n’ Roll Half.

What inspired you to start running?

I retired from NY and came here to babysit my grandchildren. My daughter Michelle was training with the Nike Run Club for the marathon. She told me about the walking group that they had, so I joined. At first it was great but after doing it for a year it was to slow for me. That's when I got into running and became a pace leader for the NWM (Nike Women’s Marathon).

How many miles per week you run and are there any special workouts you do?

Around 3 to 5; I don’t have any special workouts, I just go to the gym and train with my personal trainer. At my young age of 73, I need one.

There are so many young people who can’t even finish a 5K run and you go out there and finish another marathon! What advice would you give to people younger than you?

They need to put down their cell phone, stop playing so many video games, and go out and exercise.

What’s your goal for this year?

I have three 5k‘s, two 10k’s and three half marathons.

What do you like to do when you are not running?

I volunteer at my parish.

Who is your biggest inspiration?

My inspiration are the members of my young running family that have adopted me as I have adopted them. Whenever one of them sends me an email or text saying, “Mom, there’s a race you should come do with us!” I answer, “Where, when and how much?” They keep me young and I wouldn’t have it any other way.


Thank you “Mom” for this interview and we wish you many more happy miles. Looking forward to seeing you at our next run, as usual.
