Getting faster
Getting faster is mostly about building a bigger aerobic base, then adding one or two hard sessions a week in the right order. Runapt sets your paces from a recent race and adjusts the week as you train.

Build my adaptive race planTraining notes
Most of your weekly distance should feel conversational. Easy runs build the aerobic engine that lets you hold faster paces later without every run feeling hard.
Threshold pace is the effort you can hold for roughly an hour. Raising it moves the pace you can sustain in a race, and it is the work most runners skip.
Short, hard reps with full recovery build speed and running economy. Strides, about 15 to 20 seconds of relaxed acceleration at the end of an easy run, keep speed sharp without adding fatigue.
Most structured endurance plans keep the bulk of weekly running at an easy effort and put a small share of the week into hard work. That split, often called 80/20 intensity distribution, is a common pattern in endurance training. Runapt sequences its tempo, threshold and interval sessions around your easy volume, so speed work builds on a base instead of replacing it.
Easy does not mean slow for the sake of it. It means a pace you can talk through in full sentences. If every run is a little too hard, you lose the recovery that lets the quality sessions land.
One or two quality sessions a week is enough for most runners: a threshold session that builds sustainable pace, and, if you have the time, an interval session for top-end speed. Leave easy running between hard days, and do not stack a threshold session, an interval session and a long hard run in the same week.
Strides finish easy runs cheaply. A few short accelerations keep your legs quick and your form relaxed without turning the run into a workout.
Speed shows up in race results and time trials, so re-test every 8 to 12 weeks or after a race you ran honestly. In Runapt, a new result updates your VDOT score and every training zone with it, so your targets stay challenging without re-entering anything.
Use the VDOT calculator for a starting point, then let the training log show whether the paces are right. If the easy runs feel hard or the threshold session falls apart early, the paces are too fast and the week is adjusted.
Getting faster comes from absorbing training, not from running hard every day. Runapt tracks training load with CTL, ATL and TSB, so when load rises faster than you can recover, the plan protects easy days and delays quality work instead of forcing it.
Missed runs, poor sleep and a niggle all change what the right session is. A plan that bends around them will get you faster over a season than one that ignores them.
Build a consistent base of easy running, add one or two quality sessions a week, such as threshold and intervals, and re-test your pace every 8 to 12 weeks. Consistency matters more than any single workout.
It depends on your starting point and how consistently you train. An 8 to 12 week focused block is a common window to see a clear change. No plan can guarantee a time, but a new race result shows your progress.
No. Most runs should be easy. Hard efforts belong in one or two planned sessions a week, so you recover enough to absorb them.
Easy enough to talk in full sentences. Use the easy-run pace calculator for the exact range based on a recent race or time trial.
Yes. Runapt sets easy, tempo, threshold, interval and repetition paces from a recent race or time trial, and adjusts your week when you miss runs or your training load rises.
