We're using "Cruise Intervals" at the training I go to. It's fairly new to me but essentially we did a 1500m TT which was put through some maths to give us each our cruise interval. This is then used to set Swim Intervals we do at sessions now. Cruise Interval is then re-measured again... although I've missed this to date.
Obviously helps to have coaches who know what this is all aboot and how it works...
