Coach Ludde – Ironman Race Pace

This set is to train at Ironman (IM) race pace and control DPS during the race pace. First part of set is to find splits and stroke count at race pace.


Second part is faster than IM race pace – the first 100 you start at IM race pace and swim faster up to all in. The last part is again a 475 at maximum effort.

What goal use distance 475 All out?

I would think that Coach Ludde has chosen to go a 475 effort is due to the fact that he’s working his athletes on a set of 4×100 just before and it’s not unusual to work “over-distance” at this type of race pace training.
