I'm the North American Regional Champion for the 2nd year in a row now. Replace was a part of my supplemental regimen to achieve 2 Golds and a Silver at this Trifecta weekend (North American Regional), which made it a really good trial run for the 3 race Trifecta World Championship in Sparta. I got asked a lot about training and nutrition at these events and was happy to talk about Replace with other racers. It was great going into these events with the confidence that I had a sustained release supply of electrolytes in me and only used water stations along the course. Thanks!

All of this year up through August I was a NUUN electrolyte supplement user. It’s just what I knew and thought was somewhat effective sometimes.

I could tell even with taking them, that on long training days or long training runs, I was still tired and exhausted and my systems internally were off but I didn’t know why or what to do. Then came the Spartan North American Championship Race Weekend.

My training leading up to race was good but my body was just tired the week leading up and exhausted and muscles were stiff and slight cramps that week. The Championship race, my body did not respond well during the race and I was fighting dead legs from the start of the race. As I got further into the 13 mile race, my legs start to cramp more and more therefore resulting in a slower pace and positions being lost. I finished 29th In my age group in the Championships.

A very disappointing finish for me instead of competing for the podium spots! After that weekend, I talked to a few of my OCR buds who had taken Replace and said they liked it. I researched the supplement and analyzed my biometrics knowing I’m a bigger person in the sport of OCR than most and decided to go for it and try Replace knowing I had 5 weeks of solid training until my next Spartan Race which was the Atlanta Weekend OG October 5th & 6th.

I ordered 5 bottles of Replace and within a couple days of taking it, I could tell a significant difference in how I felt and how my body was responding! The real test was on my long run days on Saturdays. I would take a serving before the run and then later after I had finished and I felt amazing. My body wasn’t tired nor any stiffness in my legs. Then came the Spartan races which Saturday was the Super (8+mile distance) and Sunday was the Sprint (3+ mile distance) to see how I would respond from using Replace.

I’ve never felt better in a race weekend and my performance showed I finished 3rd in the Super in my Age Group and finished 2nd in the...
