First issue may be is there any snow cover ?. That pretty much closes down trails and rail trails. If no snow, I was going to suggest ride the Esposito Rail Trail that goes south from the Cuomo Bridge in Nyack (so drive and park), head down to Piermont (good town for a coffee or lunch) head back , about 8-9 miles RT, then get on the bridge path over to Tarrytown (3.5 miles one way), its a beautiful ride. Maybe then down the Old Croton Aqueduct trail just south of the bridge for as many miles as you want, its 9 miles one way to Yonkers. Its all doable (and perfect) on a gravel bike. Thats 30 plus miles. The OCA is a dirt path, flat as can be. The bridge path is paved.
