The 800m is the hardest race to train for because it is half speed and half endurance. Real 800m training builds three things in parallel: 400m speed, lactate tolerance, and aerobic base. Get one of them wrong and the race falls apart. Pair this with the 400m race strategy guide for the speed half and the 1500m training plan for the aerobic side.
Speed work for the 800m is 200s at 95-100% of mile-race pace and 400s at 800m goal pace. Two sessions per week in the speed block, dropping to one in race phase. Without this, the last 200m of the race collapses.
Lactate workouts are the heart of 800m training. Examples: 4 x 300m at 800 goal pace with 3 min rest, broken 800s (500+300), 6 x 200m at goal pace with 90s rest. These are the workouts that hurt and they are the ones that decide the race.
Even 800m runners need an aerobic base, 25-40 miles a week in the build phase, with one tempo run of 20-30 minutes. Without it, you cannot recover between hard sessions or hold pace in the second 400.
800m form breaks in the last 200m. Most runners do not see what happens because they are tucked in a pack or running solo. Upload a clip and AI flags the exact frame where head drops, arms cross, or stride shortens, then prescribes the workout that fixes it.

A 10-week peak cycle that balances all three pillars.
Easy runs 4x/week, 25-35 miles total, plus one 20-minute tempo run.
Two sessions per week: 200s at mile pace, plus a 400s ladder at 800 goal pace.
Replace one speed session with broken 800s or 4x300 at goal pace, 3 min rest.
Reduce volume 30%, keep intensity, add 100m strides and a time trial 7-10 days out.
