On his coaching journey with his team he developed individuals to be amongst the top competitors in the country. At New England, and even National Championships his athletes have captured an array of individual and team titles. Under Marks training many of his athletes have gone on to run at high level, at both High School and the collegiate level.


Alexis Lefaivre 

Alexis is a former Division I athlete on the track and field team at the University of Massachusetts Lowell. During her time there she gained invaluable knowledge about the sport not only from her time on the track but also in the class room where she graduated with a Bachelors of Exercise Science. During her time on at UML she competed on every conference championship team, even earning a championship title in the America East conference in 2023. Prior to college, Lefaivre was a 2x Vermont State Champion, 8x New England Qualifier, and 3x USATF National Qualifier. 


Asher Brownson

Asher brings a unique blend of determination and charisma to our group of coaches. Asher is a lifetime athlete who came to Marks as an avid runner. He has now transitioned to Iron Man competitions where he travels around the globe competing at the highest level. Asher is not only great with kids, but he brings along with him the attitude that anything is possible. With Asher's help, your child will leave our camp with more confidence knowing that they can achieve anything they put their minds to.


We designed the camp to introduce the fundamentals of running at the next level to the campers.

Camp sessions will start and finish at On Your Marx Running in Acton and will include a brief introduction of the sessions activity for the day.

Following that introduction we will have a short 1.5 mile run/jog through the Acton town forest (behind On Your Marx) to Nara Park.

At Nara Park, there will be more specific instruction and individual coaching.

We will then run/jog back to On Your Marx where there will be an additional follow-up discussion and individual coaching.

Camps will be two hours each day, Monday through Friday, 9am to 11am.

There will be four coaches/staff members available at all times.
