800m Training Workouts The Complete Guide

Most self-coached 800m runners run 2-3 quality sessions a week — one speed or velocity session, one speed-endurance session, and one aerobic-emphasis or tempo session — built around roughly 55-60% aerobic and 40-45% anaerobic energy demand. That's the split I coach to with BRT athletes, and it should be periodised across a season, not repeated identically week after week. Periodisation is the piece most self-coached runners, and most articles online, skip entirely. Below, I break down the four building blocks, how runner type changes the emphasis, how to periodise a training week, and how pacing and taper fit around it.

Most of the 800m programmes that stall out don't fail because the sessions were wrong — they fail because the same sessions got repeated all season with no plan for when to shift the emphasis. That's the gap this guide is built to close.

The Four Building Blocks of 800m Training

Every 800m programme I build rests on four categories of work, each targeting a different part of the event:

I name these blocks the same way with every athlete I coach, so the terminology in a training log always means the same thing week to week — worth adopting even if you're self-coached.

The Two Runner Types That Train Differently

Sprint-background athletes usually have the raw speed but lack the aerobic engine to hold it across two laps; distance-background athletes usually have the engine but lack the leg speed to close fast. Training them identically is a common mistake — each needs a different emphasis within the same four building blocks. A quick self-check: compare your recent 400m time and your 1500m or 5K time against typical 800m ratios for each — a favourable 400m relative to your endurance times points sprint-background, and vice versa.

I once had a masters athlete labelled "speed type" by a previous coach purely because he'd run track as a sprinter decades earlier. In reality his aerobic base was badly undertrained for his current event — once we rebalanced his week toward aerobic development, his 800m dropped six seconds without a single new speed session. For the full self-check and how to train each type, see find your 800m runner type.

Building a Periodised Training Week

The full weekly template, with exact session prescriptions for each day, is laid out in detail — build your periodized training week from there once you know which phase you're in.

Translating Zones Into Paces You Can Actually Run

A recent race time converts directly into training paces — a 2:20 800m runner's easy pace works out to roughly 5:30-6:00/km, for example, with VO2max reps run close to 800m race pace itself. Heart rate lags 60-90 seconds behind genuine effort, so it's a poor real-time guide on anything under about 90 seconds of work — trust pace on short reps and save heart rate for easy days. Full pace tables and the reasoning behind them are here: convert your zones into real paces.

Race-Simulation and Taper: The Final 3 Weeks

A genuine race-simulation workout — 400m + 400m with 30 seconds' rest at goal pace, run from your actual start position — rehearses the discomfort of racing, not just the pace of it, and belongs roughly two weeks out from race day. The full day-by-day breakdown of what to run across the final three weeks, including exactly when to cut volume and when to hold your last hard session, is here: race-simulation and taper workouts for the final 3 weeks.

When Training Doesn't Transfer to Race Day

Sometimes every session on paper looks right and the race result still doesn't match — that's usually down to pacing, arousal, or tactics rather than fitness, and it's a different problem from anything a training tweak will fix. If your workouts predict a time your races aren't producing, read why your race times don't match your training.

Frequently Asked Questions

How many quality sessions should I run per week for the 800m?

Two to three: one speed or velocity session, one speed-endurance session, and one aerobic-emphasis or tempo session.

What's the difference between speed, speed-endurance, and long-speed-endurance work?

Speed work is under 60m for pure velocity. Speed-endurance covers 100-300m at or near goal 800m pace. Long-speed-endurance uses 400-600m reps to hold pace into the second lap. See speed endurance training explained in depth for the full breakdown.

Do I need a track to train properly for the 800m?

It helps for pace judgement, but a measured flat loop or accurate GPS watch works if track access is limited.

What effort should my easy runs be?

Genuinely conversational — full sentences, no gasping. Easy runs build aerobic capacity and aid recovery, not add fitness through effort.

When should I stop hard sessions before a race?

I pull the last genuinely hard session 6-8 days out, not the generic two weeks you'll see quoted elsewhere.

How does a distance runner transition into 800m training?

Gradually — keep the aerobic base you've already built, and add short speed and speed-endurance work progressively on top of it.
