What Is the 75 Hard Challenge?
75 Hard is a 75-day mental toughness program created by Andy Frisella. Every single day, with zero substitutions, you complete five tasks: two 45-minute workouts (one must be outdoors), drink one gallon of water, follow a diet of your choice with no cheat meals and no alcohol, read 10 pages of a non-fiction or personal development book, and take a daily progress photo. Miss any task, even once, and you start over at Day 1.
How the Finish Date Is Calculated
The math is simple but unforgiving. Day 1 is your start date, and the challenge runs 75 consecutive calendar days, so the finish lands 74 days after you begin. This tracker counts the days elapsed since your start and adds one so the morning you begin is Day 1, not Day 0.
finishDate = startDate + 74 days; dayNumber = floor((today - startDate) / 1 day) + 1
The Numbers Behind 75 Days
Over a full run you log 150 workouts at 45 minutes each, which is 112.5 hours of training. You also read 750 pages, roughly two to three full books, and drink about 75 gallons of water. Seeing those totals climb in real time is part of why a day-by-day tracker keeps people honest. There are no rest days and no partial credit, which is exactly what makes finishing 75 Hard a genuine accomplishment.
Frequently Asked Questions
What happens if I miss a task on day 40?
You restart the entire challenge at Day 1. 75 Hard has no rest days, makeup days, or partial credit, which is the whole point of the program. Reset your start date in this tracker to your new Day 1 and the finish date will recalculate automatically.
Do both workouts really have to be separate?
Yes. The rules call for two distinct 45-minute workouts each day, and at least one of them must be outdoors regardless of weather. You cannot combine them into one 90-minute session, because separating them builds the discipline of returning to the work twice.
Does the gallon of water include coffee or other drinks?
No, the gallon refers specifically to plain water. Coffee, tea, and other beverages are extra and do not count toward the one-gallon daily requirement. Most people spread it across the day using a marked jug to stay on pace.
Can I do 75 Hard if I travel or get sick?
The program is intentionally rigid and makes no exceptions for travel, illness, or holidays, so you complete every task or restart. Many people plan their start date around known disruptions, and you can preview where any start date lands before committing to it.
Practical Guide for 75 Hard Challenge Tracker
The hardest part of 75 Hard is rarely the workouts. It is the relentlessness. Because a single slip resets you to Day 1, the program rewards preparation over willpower. People who finish tend to plan the next day the night before: clothes laid out, water jug filled, reading book on the nightstand, and both workout windows blocked on the calendar.
The two-workout rule with one outdoors is what separates 75 Hard from a normal fitness plan. The outdoor session forces you to face weather, cold, and inconvenience, which is where the mental toughness actually gets built. Walking counts, so the second workout does not need to be intense; it needs to happen, every day, without negotiation.
Use this tracker as a daily check-in. Watching your day number tick up and your percent-complete bar grow gives the streak a tangible value that you become reluctant to break. Pair it with the daily progress photo, because the visual change from Day 1 to Day 75 is often more motivating than the scale.
