Enter Your Time Trial Result At the End of The Challenge:

[gravityform id=7 title=false description=false]

Thus far we have challenged you to increase your swim efficiency, improve your core, swim faster, and now boost your endurance. To do this, we are going long! 

Unlike the previous challenges where we had one group doing the same workout, we are going to have two levels: 

500 and 1650 

Choose the distance that you feel meets your goals as an athlete (think about your race lengths) as well as your ability (beginners may want to start with the 500s). Remember it is called a challenge so be honest, but do not underestimate yourself.

Both groups will do:

1. A time trial (TT), which will then determine your paces for the rest of the 21 days

2. Then do 2 workouts each week and one drill set. We only provide the main set which can be tacked on to your regular workout or done by itself. Just be sure that you are warming up properly if this will be your only set.
