Built on 20+ Years of Developing Elite Athletes
Les Spellman co-founded The Performance Lab on a simple belief: every athlete deserves coaching that's personal, measurable, and built on real science — not gym-bro trends.
Les has spent over two decades coaching athletes at every level — from middle-schoolers discovering their first sport to NFL draftees, Olympians, and professional soccer players. He's the coach behind Cat Macario's development from age 14 through Stanford records and the U.S. Women's National Team.
As a Certified USR Speed Lab coach, Les has built The Performance Lab's methodology around one idea: take the guesswork out of getting faster. Every sprint is timed. Every session is logged. Every cycle, athletes see their numbers move — and those numbers are verified against the largest youth-speed dataset in the country.
Spellman Performance × Surf Soccer
We've partnered with Surf Soccer to unite under one mission: transform youth athletic development. Every Performance Lab athlete gets world-class training focused on performance and recovery — right inside Surf Sports Park, where club soccer and serious performance training finally live under the same roof.
One Standard. Every Athlete.
Raise Your Game.
USR is the speed intelligence platform that standardizes how athletes measure, develop, and rise.
Why Every Athlete Needs a USR Score
A stopwatch time from one coach's clock doesn't travel. A Universal Speed Rating does. One protocol. One standard. One number that means something in every sport, at every age, in every city — backed by the largest verified speed dataset in youth athletics.
Ranked #1 Speed Lab — SSI Network
64,920 verified assessments. The Performance Lab sits at the top of the Speed Science Institute's Top 10 Speed Labs — more timed, tracked, and verified athletes than any other facility in the USR network.
Same Protocol. Everywhere.
Combine numbers and coach-watch times depend on who ran the clock. The USR uses one protocol — the same timing gates, the same splits, the same setup — so a 20.2 MPH MaxV in Del Mar means the same thing as 20.2 MPH in Dallas or Atlanta.
Age & Sex Normed.
Your athlete's USR score comes with benchmarks against 125,000+ peers. No more vague "fast for their age." You get the exact percentile, the exact gap to the next tier, and a concrete plan to close it.
Verified. Not Self-Reported.
Every USR data point is captured through certified timing gates and logged by a Certified Speed Lab. Recruiters, club programs, and college coaches trust it because they can audit it — all the way back to the session.
"With nearly a million verified data points, we finally have the volume to stop arguing from anecdote and start building training around evidence."
Dr. Ken Clark — Speed Science Institute
"Speed is the most transferable skill in sport. The USR gives every athlete a number — and a path to move it."
