Daniels Cruise Intervals
5–6 × 1 mile at threshold, 60 s rest
Collection
The 'Norwegian model' — the double-threshold approach whose best-known proponents are the Ingebrigtsen brothers — keeps threshold running controlled and splits it into many reps with short rests, often twice in one day. These are the sessions from the model's published sample week: 5 × 2 km, 5 × 6 min, 10 × 1 km and 25 × 400 m at a controlled threshold, plus 20 × 200 m hill sprints. Jack Daniels's cruise intervals, threshold repeats with short recoveries, round it out.
5–6 × 1 mile at threshold, 60 s rest
10 × 1 km at controlled threshold, ~60 s rest
25 × 400 m at controlled threshold, 30 s rest
5 × 2 km at controlled threshold, 1 min rest
5 × 6 min at controlled threshold, 1 min rest
AM: 5 × 2 km controlled · PM: 25 × 400 m — this is the AM half
20 × 200 m uphill, jog down
