Running should be play. You should have fun doing it. Considering that goal, competing in running races can be intimidating at first, but I think you would enjoy doing just that. If you've been reading between the lines on the daily training guides this week, you'll notice that I've been nudging you toward the starting line of a 5-K race this weekend. If so, it is appropriate that you rest today, whether your race is Saturday or Sunday, or even if you don't race.
Rest is always an important component of any training program.
It doesn't matter how far you walk or how fast you walk. I just want you out today stretching your legs and burning a few more calories. Sometimes it helps to take a full day of rest before you race, particularly an important one. If that's the case, schedule your walk for Friday and rest today. Similarly, depending on the local race schedule, it may be easier to find a 5-K race nearby on Saturday rather than Sunday.
