Training for a marathon changes the way you think.
You stop worrying about one great workout and start thinking about stringing together hundreds of good ones.
That's exactly how Nutristat athlete Walter Lazo is preparing for the 2026 Marine Corps Marathon, one of the largest marathons in the nation.
Walter didn't grow up as a distance runner. After years of playing soccer, he found his stride by blending endurance training with heavy strength work. Today, his weeks are filled with long Zone 2 runs, track intervals, gym sessions, and recovery, all with one goal in mind: arriving at the starting line healthy.
As Walter puts it:
"Success isn't just about finishing with a new personal best. It's about staying consistent, avoiding injuries, and becoming mentally stronger. Consistency compounds."
Train Strong to Run Strong
One thing that surprises people about Walter's routine is how much time he still spends in the weight room.
His favorite exercise?
Bulgarian split squats.
They're not glamorous, but they build the single-leg strength, balance, and hip stability that every runner depends on. When you're thousands of strides into a marathon, those small stabilizing muscles become a pretty big deal.
Walter's advice is refreshingly simple:
"Don't rush your fitness. Build a strong aerobic base first, stay patient, and focus on consistency."
The Marathon Endurance Stack
Training is the hard part.
The stack is there to help support it.
After long runs, Walter reaches for PÜR NATIVE to kickstart recovery before the next session.
Creatine and Crea Script help support ATP production, strength, and performance so he can continue balancing heavy lifting with increasing mileage. Both are built around Creapure®, one of the most respected creatine sources in sports nutrition, because if you're taking something every day, quality matters.
During longer training blocks, Amino Script helps round out his routine with essential amino acids to support recovery as the miles continue to add up.
More Than One Race
Walter still has plenty of miles ahead before October.
Over the coming months, we'll be following his training, recovery, and race-day preparation to show what it really takes to get ready for 26.2 miles.
There's no secret workout.
No magic supplement.
Just consistency, good habits, and the right tools to support the work.
If you're training for your own race, chasing a new personal best, or simply trying to stay active, that's a philosophy worth borrowing.
