The plan for the last two weeks has been to start building my weekly mileage. This week the goal was 32 miles and officially beginning the 16-week half marathon build. This week included three key pieces of training: 400m repeats, rolling 400s, and a progressive long run. Tuesday: 400m Repeats I ran 8 × 400m at around 5:40/mi pace with 1 minute walking rest between reps. I did this workout midday, and it was really hot, which made it tougher to hit the pace consistently each rep. Workout Purpose: 400m Repeats - Introduces faster running in short, manageable pieces - Helps you practice running quicker than easy pace without holding the effort for very long - Walking rest allows recovery so each rep stays controlled - Goal: run fast, walk to recover, and finish feeling like you could have done a little more Thursday: Rolling 400s Thursday was a similar workout, but with less full recovery. This workout was 400m at 6:35/mi pace followed by a 400m float at 7:45/mi pace, repeated 4 times. Workout Purpose: Rolling 400s - Teaches you how to change paces while still running - Alternates faster 400m reps with controlled 400m float recoveries - Builds speed endurance without fully stopping between reps - Helps you practice staying relaxed when the pace changes, which is useful late in races - Goal: run fast, stay controlled during the float recoveries, and finish feeling strong Saturday: Progressive Long Run Saturday was a progressive long run: - 3 miles easy - 3 miles at 7:35/mi pace - 2.5 miles at 7:10/mi pace - 1 mile easy Total: 9.5 miles This one felt good. It was nice to pick up the pace in the middle of a longer run and challenge myself without turning the whole run into a race. Workout Purpose: Progressive Long Run - Builds endurance while practicing faster running later in the run - Starts controlled so you can settle in before picking up the pace - Teaches you how to run strong when your legs are already a little tired - Helps build confidence for race day pacing - Goal: start easy, progress with control, and finish strong without racing the workout
