One thing about the "donation" you make for the massage, 100% goes to the local children's hospital in Orlando.
The massage therapists are either students or trainers, who all volunteer their time. Any tips you add, go right into the "donation jar"!
I didn't need it after the half marathon, but I did a 10 minute stretch and massage after the full.
As I was about to lay on the table, I made a comment to the gal, about all my sweat and salt covering me. She told me don't worry about it, they're so used to it, they don't even smell it anymore.
I find the 10 mintue stretching and massage does help the recovery.
Having a full spa massage a day after a race is even more enjoyable, since it's usually 50 minutes.
Most of all, keep moving after your races. Don't go back to the room, shower, sit around or go to sleep. Stay active to keep the muscles in motion.
