Zac Efron knows the importance of family.

The Greatest Showman star didn’t let the rain bother him as he made his way to the Boston Marathon to support his brother.

Dylan Efron was running the race for the first time and completed the endeavor in 2 hours and 57 minutes.

Along the way, he had a brilliant cheerleader (perhaps he can thank all that time in High School Musical) encouraging him from the sidelines.

In a video posted on Instagram, the 30-year-old actor can be heard cheering his brother on as he crosses the finish line.

Zac states in the caption, “Ima be at every [race] with you from here until forever, Brother,” which is enough to melt hearts everywhere.

As if that wasn’t enough of a display of brotherly love, the video also shows Zac embracing his younger sibling, who posted his own Insta pic saying that Zac waiting for him at the finish line was all the motivation he needed.

Mr. and Mrs. Efron must be so proud.
