There's nothing that can be biked to/ from the Y, other than pavement or gravel road in under 3 hrs
Crosier Mtn is the closest ST, although that will require a car and is pretty techy in spots, but is an awesome ride that can be done in that time frame.
If you really want to sandbag it, have somebody drive you to the top of Trail Ridge Road at dawn, and then coast down from 12,000' to the Y.
I got lucky last weekend. My son's wedding was a 5 min drive down to Dadd's Gulch up Poudre Cyn.. My oldest brother and his family are all trail runners so I ride and they'd run the trail the 3 mornings we were up there.
