It is nice to have choices, although none will be as convenient as Crossfit Golden was from the CDOT Golden Office which was less than 250 yards away. Crossfit Train will be the closest at a mile away and seems to have a good community based on the Facebook page.
There also seems to be good walking and bicycling trails.
Finally there is also a fitness center on site that I am anxious to check out.
Light rail goes right past the building as well.
Other gyms to check out. Discount with GEHA
