Threshold Progression Sets
These types of workouts will help boost your race-day fitness thresholds by running hard for relatively short distances at speeds faster than race pace with short rest.
When: Once every few weeks during a marathon race buildup.
How: After a thorough warm-up, run 3 x 3-mile repeats, running the first mile of the three-mile segment at marathon pace followed by a one-minute jog. Run the second mile at half-marathon pace followed by a one-minute jog, and run the final mile at 10K race pace. Jog easily for three minutes after the set, then repeat the set twice more at the same pace.
