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
Strength Training
Monday - Upper Body
Wednesday - Lower Body
Thursday - Upper Body
Overall, this was a solid first week of the half marathon build.
I hit the main workouts, got in the mileage, kept strength work in the plan, and finished the week healthy enough to attack week 2
