About this plan

This 8 week half marathon training plan opens with 26 mi in week 1 and peaks at 33.5 mi in week 6. Halfway, week 4 carries 22 mi with a 8 mi long run. That is 207 mi over 32 runs for an intermediate half marathon runner. Cutbacks: week 4 (22 mi).

11 key sessions — 2 hill, 2 fartlek, 4 tempo and 3 interval — back up a long run that reaches 12.5 mi in week 6. Easy running at 9:28–10:25/mi is 71% of the 207 mi; 4 threshold sessions run at 7:53/mi. Race-pace reps at 8:07/mi arrive once the long run passes 10 mi, late in the 8-week block.

The 2-week taper takes race week to 11.5 mi, 66% under week 6's 33.5 mi, after 207 mi. Projected finish after 8 weeks and 207 mi: 1:46:22 for the half marathon (8:07/mi).

4 sessions and 26 mi open this 8-week plan, topped by a 9.5 mi Sunday.

The phases run base weeks 1–2 (26–28 mi), build week 3 (29.5 mi), peak weeks 5–6 (31–33.5 mi), taper week 7 (25.5 mi) and race week 8 (11.5 mi).
