All through construction, the auxiliary gym at the Silverthorne Recreation Center has been split down the middle. One half holds the gymnastics program and its equipment. The other half is a multipurpose gym for drop-in sports and the fitness classes that lost their usual rooms to the build. That split is the reason the $29 million expansion is being built. It also explains where the new court time will actually come from.
The biggest piece of the 24,690-square-foot addition is a 12,140-square-foot Multi-Activity Court gym, known as the MAC gym. Most of it is designed for gymnastics, parkour, silks and trampoline. The basketball, volleyball and pickleball hours drop-in players have been waiting for will open up in the original gym once gymnastics moves into the new building.
Three sections, and only one for courts
The Town describes the MAC gym as three flexible zones. One is for court sports and overflow. One is for gymnastics, parkour, ninja and aerial silks. The third holds a trampoline, a tumble track, a pit bar and a foam pit. A spectator lounge overlooks all three. The Silverthorne Storm Gymnastics team, which has shared the original gym since the building opened, gets a permanent home there along with youth and adult classes in silks, parkour, trampoline and tumbling.
Mason Greathouse, the Rec Center's sports coordinator, put the change simply in a Town of Silverthorne feature on the MAC gym: "We have a ton of equipment that we move around, so this will be a great addition. Many things, like the gymnastics equipment, will finally have a permanent home."
The same feature says that a dedicated gymnastics space plus an extra auxiliary gym will leave the existing gymnasium "more available for open gym time, court sports, drop-in recreation, and new youth and adult sport leagues." Summit Daily's July 12, 2026 report says the same thing. Giving gymnastics its own space frees the original gym for more drop-in basketball, volleyball and pickleball.
That project has been a long time coming. The Rec Center was built in 1992 and opened in 1994, and the Town first called for an expansion in its 2009 recreation master plan. Steven Herrman, the Town's parks, recreation, open space and trails director, told Summit Daily that programs have regularly been full, and people trying to get in are "in a kind of silent line, or waitlist."
The court hours have no schedule yet
Gymnastics can't move until the building is finished, and as of late October 2026, the building has no completion date on the calendar. Drop-in basketball is still on the indoor gym schedule. On October 19, 2026, for example, it showed full-court adult drop-in basketball from 6 to 9 p.m. The Town has not posted a schedule for after the opening, and it has not announced start dates for the new leagues.
The latest official timing comes from an October 14, 2026 memo to Town Council. It says the project has entered its final finish and closeout phase and "remains on track for November 2026 completion." It also says the elevator shaft and inspection are a current schedule risk, because code-related improvements may be needed before the elevator gets final approval. November is the target month for completion. No public opening day or ribbon cutting has been announced.
The total project budget is still $29 million. The September status report shows a $24.384 million guaranteed maximum price contract after approved changes, and $346,859 in owner contingency before pending items. The whole project is paid for by Silverthorne's 8% lodging tax.
The childcare dates are set
Camp Silverthorne, the first licensed childcare program the Town will own and run, follows the Summit County School District calendar. Its dates are already posted, and they are the firmest dates connected to the expansion. Here they are, alongside the regular winter calendar change:
- Sunday, November 1: Winter weekend hours begin. The center opens 7 a.m. to 9 p.m. on Saturdays and 8 a.m. to 9 p.m. on Sundays through May 31. Weekday hours stay 5:30 a.m. to 9 p.m.
- Tuesday, November 10: Enrollment opens for Camp Silverthorne's holiday-break sessions.
- Tuesday, December 1, 7 a.m.: Registration opens for winter after-school care.
- December 21–23 and December 28–30: The first two Camp Silverthorne sessions run during the district's holiday break.
- January 5, 2027: After-school care starts.
The program is open to kids ages 5 to 12. Five-year-olds must have started kindergarten. All-day camp runs 8 a.m. to 5:30 p.m. for $55 a day. After-school care runs until 5:30 p.m. for $15 a day on Monday, Tuesday, Thursday and Friday, and $20 on Wednesday, with transportation from Silverthorne Elementary School. Most programs allow day-by-day registration, and the Town offers scholarship funds. Summit Daily reported room for up to 45 children, and the Town has hired Megan Fisher, a Summit County resident, as its licensed programs coordinator.
Camp Silverthorne gets 2,370 square feet of the addition. It is a much smaller footprint than the MAC gym, and it is the part of the expansion most tied to a fixed calendar.
The other new rooms
The rest of the addition goes to spaces that regulars will use every week, once crews hand the building over. Here's how the Town has described each one:
| Space | Size | What the Town has described |
|---|---|---|
| Weight Room 1 | Part of 1,440 sq. ft. of expanded weight room space | 39 fitness stations, new flooring, park-facing windows, Atlantis hack and power squats, cable machines, TKO pre-weighted curl bars |
| Weight Room 2 | Part of the same allocation | Lighter-weight and functional-fitness room with 12 stations, a Torque rack with rope pull and ski erg, a cable machine, and a Torque sissy squat |
| Smaller multipurpose room | Part of 2,500 sq. ft. for two rooms | About 15 people classroom-style, for programs, meetings and rentals, with patio access |
| Larger multipurpose room | Part of the same allocation | About 50 people, for cooking, toddler and leisure classes and rentals; overlooks the gym and can connect to a kitchen |
| MAC viewing lounge | 1,970 sq. ft. | Seating that overlooks the MAC gym |
Town staff have said more yoga, more Muscle Madness, and new toddler, school-age and cooking classes will follow once the building is complete. No launch dates have been published for any of them. The two new rooms will let the fitness classes now held in the gym move out. That is the second way the expansion frees up the original gym for court sports.
What goes back to normal at handover
Some temporary arrangements have been in place long enough to feel permanent. According to the Town, the indoor track is closed for walking and running, with only part of it open for cardio and circuit equipment. Weight Room 1 is closed, with its equipment spread between Weight Room 2 and the Aerobics Room. Fitness classes are held in the gymnasium. Kid's Korner is running out of a dedicated area in the lobby. Kid's Korner offers short-term care for children ages 6 months to 6 years, up to two hours per child per day, while parents use the facility. Its redesigned room adds windows, new flooring, a better entrance and direct patio access.
Outside, the road behind the center to Rainbow Park has been closed to the public throughout construction. Parking behind the building for the tot lot and volleyball courts is closed as well. For now, the park is reached from Rainbow Drive, the Rec Center's front lot, or the Rainbow Park lot. The new gymnastics space will have its own parent drop-off entrance on the building's east side, with added street parking facing it. That separate entrance will keep gymnastics pickups apart from the main lobby where drop-in players come and go.
The September status report expects no major operational disruptions from here on, apart from brief interruptions for testing, move-in coordination, and minor lobby work to remove the temporary Kid's Korner. Admission is unchanged for now: $16 for adults, $9 for youth and $14 for seniors per day, with monthly passes at $68, $42 and $50 and a $160 family monthly pass. The Town has not announced any price or hours change tied to the expansion.
A building on Rainbow Drive that gives every activity its own room, where the gymnastics equipment no longer moves and the gym is left for courts, is the kind of practical design thinking Marty Frank looks for in the homes around it.
