I'm aiming (crossed fingers) to do my first HIM in September. For those of you who have done longer distance tris, how important is it to have done each of the individual distances before the race? I've done the swim length and today my SO and I rode 55 miles. But I don't know if I'll be able run 13 miles before the race. Is it more important for me to keep working on it or to go for shorter bricks?
