Last year, I crossed the finish line of the Boston Marathon. No, I’m not an elite marathon runner. I crossed the finish line after a day touring the city of Boston in October, not on race day. It still was exciting to be on the spot where so many top runners have set personal records and breathe a sigh of relief after more than 26 miles pounding the pavement. Just down the road from the racecourse is The Spa at Mandarin Oriental, Boston, which offers its own brand of revitalization tailored for runners. The spa is bringing back the Marathon Boost treatment ($200, 80 minutes) for the month of April in honor of the 120th Boston Marathon, which takes place on Monday, April 18. This full-body massage relieves aching legs and releases muscle tension throughout the body. Personalized techniques cleanse the body of lactic acid and relieve overworked joints and limbs. It incorporates the Signature Release massage oil made with cypress, eucalyptus, clary sage, juniper berry, frankincense, pine, and jasmine. This therapeutic blend is proven to dissolve stress. To finish, a gel made with warming rosemary, black pepper, lavender, and ginger is applied to the body to relieve tense muscles. Marathoners will want to set aside extra time to relax before and after the treatment to take advantage of the spa’s thermal facilities. Separate men’s and women’s heat and water facilities each feature a quartz crystal steam room, vitality pool, experience showers, ice fountain, and relaxation lounges. The Spa at Mandarin Oriental, Boston isn’t the only relaxation spot offering specials for runners, check out more creative ways Boston spas are pampering marathoners.
