182aa

Run smarter, plan better, and keep your training on track.

182aa is a clean, offline training companion for runners. It brings together practical calculators, structured training plans, a running knowledge base, and a simple run log — all in one place, with no account required.

Use the built-in tools to plan workouts, estimate race times, and understand your training numbers. Calculate pace, time, or distance; predict race results across common distances; find training paces from a recent race using the VDOT method; build even or negative split plans; estimate heart-rate zones with Karvonen or %max; and convert between kilometers and miles.

Follow structured plans for every stage of running, from your first 5K to a full marathon. You can also use base-building plans, return-to-running plans, and trail or hill-focused plans to match your current goal and fitness level.

Learn the fundamentals of better running with a practical knowledge base covering form, training, nutrition, injury prevention, and race preparation.

Track your progress with a simple run log. Record each run, monitor weekly distance and pace, and keep an eye on your personal bests as your fitness improves.

182aa works fully offline. Your data stays on your device, with no account, no sign-up, and no tracking. You can export or import your data whenever you need.

All calculator results are estimates for training guidance and are based on established running formulas.
