Taking time to unwind and stop training (and stop thinking about training) is important. Most coaches recommend a period of at least three weeks after your last race to hang up your superhero costume and live life like a regular (non-triathlete) person. It’s that not you should be a complete slacker and fall into bad habits, but it’s a perfect chance to make up for the everything you missed during your busy season of training and racing such as going to the movies, cleaning out your garage, reading a good book or spending time with your significant other or family.
But that doesn’t mean you should be a total veg when it comes to exercising. Use this time to be healthy in a comfortable, non-obsessive way. Stay active, but don’t think about workouts. Just do what you feel like. That might mean jogging three miles with a friend from work. Or simply running around a local park for 15 to 20 minutes. But don’t wear a watch or keep a training log.
