Pace Intervals (PI) Working at you half marathon goal pace. This will help establish where you should be race day.
Cruise Intervals (CI) Run at 10k pace to promote the ability to sustain pace and run while tired. For 10'/mile pace (2:11:06 finish) practice at 7:07 (1200) 4:45 (800); for 9' (1:57:59) 6:24 (1200) 4:16 (800); for 8' (1:44:52) 5:42 (1200) 3:48 (800).
Speed Intervals (SI) Run at 5k pace to promote relaxed speed. This will help you run at your slower half marathon pace more comfortably. For 10'/mile pace (2:11:06 finish) practice at 4:30 (800) 2:15 (400) 1:07 (200); for 9' (1:57:59) 4:04 (800) 2:02 (400) 1:01 (200); for 8' (1:44:52) 3:37 (800) 1:48 (400) 0:54 (200).
