Have you ever not trained for a race because you weren’t sure what your schedule would be, and thus if you could fully train?
Have you trained for a race and then not been able to do it?
Which feels better to you?
We will never have all the answers as to what the future holds. Might as well live the life and let the pieces fall; and if you cannot compete or if you end up not being able to train sufficiently for a race, at least you had experience along the way and just be kind with yourself and train for the next one.
