DEKA FIT Guadalajara

Come for the training, stay for the amber light of a Castilian autumn: the Palacio Multiusos sits minutes from the old town, where you can walk the arcaded Plaza Mayor after the workout and warm up with a plate of migas or roast suckling pig at a local mesón. October in Guadalajara is crisp and quiet, so you get the city's Roman and Renaissance layers—from the Palacio del Infantado's Moorish ceilings to the bridge over the Henares—without the crowds, and the regional wine from the nearby La Alcarria hills is a perfect evening reward.
