A nice splurge-y option: Bliss Spa's new Extreme Sports Massage ($145/60 min., $205/80 min.), which aims to send overworked muscles to a relaxed state. The massage starts with a warm parafango pack, moves into a deep tissue rubdown, and finishes with a perk-you-up gel. If you've made it through a marathon, don't forget your race number; show it off at any Bliss location (except) for DC, Boston, and Fort Lauderdale) and you'll receive a free Foot Patrol cream. After 26.2 miles of running, you'll need it.
