It has been encouraging to see many of you at the facility during our first few days of operation. As you may have noticed, a few projects are still being completed throughout the building. Most projects will not impact your experience at TPAC. However, next week the indoor track will be closed from Monday, January 11 through Wednesday, January 20 so the lines to separate the lanes can be painted.

During the closure, track only members will have the option to either use a treadmill in the fitness center or walk the gymnasium. Track only members should continue to use the track registration slots to reserve their visit to TPAC. If there is flexibility in schedules, members are encouraged to avoid the busiest sessions (9:30am & 3:30pm). Fitness members will also have access to the gymnasium. If other programs and users are in the gymnasium, the flow of traffic may be limited to the perimeter and will be clearly marked.

This work was originally planned for early December, however, the company was delayed due to COVID-19.
