Youth speed training sounds like something only serious recruits need, but most of it is a plain skill lesson. Sprinting fast, stopping without wrecking a knee and cutting in a new direction are movements a child can be taught, just like dribbling. A good program covers sprint mechanics, acceleration, deceleration, jumping and landing, and enough basic strength to hold those positions as the athlete grows. The local operators split their programs at about the same age. Kids from roughly seven to twelve get group sessions built on coordination and play, and athletes from middle school up get individualized strength and speed work. That split is the most useful thing to know before you pay for anything.
The second thing to know is where the gyms actually are. We searched for youth speed and athletic development across Boulder County and found exactly one dedicated youth performance gym with a Boulder address, and it is in Gunbarrel. Three of the other four programs below are in Longmont, and two of those grew out of physical therapy practices. The fifth is on the Erie side of the county line. Much of what ranks for “Boulder youth speed training” is in Castle Rock, Littleton, Centennial, Windsor or Denver. We cover those at the end so you can recognize them. Every schedule, age range and price below was read on each business’s own site on September 21, 2026.
In The Core Athlete — the Gunbarrel gym with a Monday young-athlete group
In The Core trains out of 5455 Spine Road, Suite F, in the Gunbarrel business park, and it has a Boulder address. It publishes a group price: $22 per athlete per session in a 10-class package, or $30 as a drop-in, for 70-minute sessions with 10 to 15 athletes and one coach. The open group running now is a young-athlete session on Mondays from 5:00 to 6:10 p.m., with no minimum commitment. Club teams can book closed blocks with a 10-week minimum, priced by quote, and the gym lists REAL FC, St. Vrain FC and Rush Soccer Club among the teams it has trained. The site is frank that groups do not get the building to themselves, because its one-on-one “Elite” sessions run at the same time. Its pages list a minimum age of six or eight, and founder Aaron Vogel runs a phone intake first, so ask him which applies.
NOCO Performance — a Longmont strength gym with a class just for seven- to twelve-year-olds
NOCO Performance is a strength and conditioning gym at 1623 Vista View Drive in east Longmont (80504). It runs its youth work as two separate programs, which makes it easy to see what your child would be doing. “Youth Athleticism” is for ages seven to twelve and meets Tuesdays and Thursdays for an hour. The listed focus is coordination, teamwork and performance tracking, not heavy lifting. “Sports Performance” is a semi-private program for middle school, high school, college and pro athletes, held every day, and it lists speed, power, strength, vertical and broad jumps, and running form. Membership pricing comes from the team, and a free trial class is the way in. Adults train in the same building, and the gym also runs a recovery lounge with a sauna and cold plunge. That makes it a practical choice for families who want one membership location for parents and kids. The contact listed is coach Johnny Baisley at (303) 590-8509.
Crafted Training — a physical therapy clinic’s youth program on Delaware Avenue
Crafted Training is the youth athletics arm of Crafted Physical Therapy, and both share the address 701 Delaware Avenue, Suite D, Longmont, phone (720) 204-4567. The program says it started because staff saw young athletes arriving at the clinic with injuries they felt better preparation could have prevented. Sessions cover six areas it names outright: speed, power, stamina, core strength, strength and flexibility. The staff list is the main reason to look here. More than ten people are named, and the studio describes most of them as certified strength coaches who are also physical therapists or physical therapist assistants. Sports named on the site run from soccer and baseball to climbing, gymnastics, cheer and skiing. Signup is a web form that asks a parent or guardian to register the athlete; call to ask about the schedule, ages and what a season costs.
AAFY — Longmont performance training supervised by physical therapists
AAFY Physical Therapy and Performance Training is at 65 Sugar Beet Circle in Longmont (80501), and it approaches youth speed from the rehab side. Founder Dr. Will Trujillo writes that he played college football at Adams State and worked as a collegiate strength coach and in pediatric rehab before opening the clinic. The performance page says it trains youth and adult athletes, and it frames speed, power and change of direction partly as injury resilience, especially for collision sports like football. Group sports performance training, for a position group or a few friends, is described as “overseen by our doctors,” with pricing that varies by group size and must be requested. The one hard published number is $350 a month for an individualized remote program. This is a good fit for a teenager coming back from an injury who needs a return-to-sport plan more than a speed class.
LGC Athletics — Breakaway Speed on the Erie turf
LGC Athletics runs out of the Legacy Lacrosse Center, an indoor turf building in Erie, and its site uses both names. Its youth speed program is called Breakaway Speed, for athletes eight to twelve or thirteen. It covers sprint mechanics and starts, deceleration and change of direction, jumping and landing, and bodyweight strength basics, and it is pitched to players of any sport, not just lacrosse. Older athletes move into semi-private training, capped at four per session, for seventh grade through college, or into private one-on-one coaching. LGC also runs a Legacy Speed Combine in two brackets, first through sixth grade and seventh through twelfth, which gives a family a timed baseline. Ask about pricing when you book. Two practical notes: the building is on County Road 3, on the Weld County side of Erie, not in Boulder County. LGC also runs a second location at 12500 Huron Street in Westminster, so confirm which one a session is at.
What Ranks for “Boulder” but Isn’t Here
Search results for Boulder youth speed training are crowded with programs that are an hour’s drive away. Colorado Performance Factory’s youth speed page is in Castle Rock. Team Speed, whose spring youth classes for ages seven to twelve ran $647.50 for the season, is on East County Line Road in Littleton. Simple Speed Coach is in Windsor, and Landow Performance is in Centennial, along with several Denver speed gyms. None of these is a bad program, but none is a weeknight option for a family in Boulder or Louisville. National marketplaces also run Boulder landing pages that list traveling coaches rather than a facility.
Before You Book
Start with age, because it decides which of these programs you are actually shopping for. For a child under about twelve, look for a group class where speed is taught as coordination and play, like NOCO’s Youth Athleticism, LGC’s Breakaway Speed or In The Core’s Monday group. Ask how many kids one coach handles. For a teenager, ask whether the program tests anything. A timed 10-yard dash or combine gives you a before-and-after number instead of a feeling. Ask who is coaching and what credential they hold. Two of these programs are run by physical therapy practices, which matters most if your athlete has had an injury. Ask for the total cost of a season, not a per-session number. Then ask whether the athlete trains alongside older athletes or adults, since several of these gyms share the floor. Finally, map the drive. From central Boulder, Gunbarrel is the short trip, and Longmont and Erie are the evening commute.
