He uses acronyms constantly without having a glossary of useable index. Can you help? CTS And, more importantly, when he describes over under intervals in his training regime he writes: 60-90 min EM with 3x8 min OU (3U,10) (6 min RBI) I translate as 60-90 min endurance pace, with 3 eight minute efforts and 6 minutes between them. But what the heck is OU (3U,10)???? 3U must mean 3 of the 8 minute efforts are under, but what the heck does that 10 mean???? Thanks!

So, in the example you've given, you'd only do 24-54 minutes at endurance pace. Regarding the "OU (3U, 1O)", that would be "overunder intervals" (described on pg. 119 of my edition of the book). That's the letter "oh," not the digit zero. Basically, each 8 minute interval would consist of 3 minutes "under" (86-90% of field test avg. power), 1 minute "over" (95-100%), 3 minutes under, and 1 minute over. You always end with an "over." I agree, his notation can be kind of confusing at first; but after a while you begin to see the logic of it. Now if only I could motivate myself to actually follow one of his plans...

Got it. Thanks. My book says under at 92-94% max sustainable heart rate, and over 100% max for the over. So I went and did it.
