Calculate your 75 Hard, 75 Medium, or 75 Soft challenge end date. See a visual 75-day calendar, daily requirements, challenge totals, and a side-by-side comparison of all three variants.
How To Use This 75 Hard Calculator
Choose your challenge variant (75 Hard, 75 Medium, or 75 Soft) from the dropdown, then pick your start date. The calculator instantly shows your Day 75 completion date and generates a visual calendar of all 75 days laid out week by week, so you can see exactly which dates you need to commit to.
If your start date is today or in the past, a progress bar shows which day you are currently on and your completion percentage. The daily requirements section lists every rule for your chosen variant, and the challenge totals show cumulative numbers like total workouts, water intake, and pages you will read over the full 75 days.
Scroll down to see a side-by-side comparison table of 75 Hard vs 75 Medium vs 75 Soft. This helps you decide which variant is right for your fitness level: 75 Hard is the strictest (two daily workouts, one outdoors, no cheat meals, full restart on any missed day), 75 Medium is more forgiving, and 75 Soft is the most flexible starting point.
Why Picking The Perfect 75 Hard Challenge Start Date Matters
The 75 Hard challenge is unforgiving. Miss a single task on any day and you restart from scratch. That means your start date is not just a number on a calendar, it is a strategic decision that can make or break your entire attempt.
Use the calculator above to map out your 75 days, then look at what falls inside that window. Got a wedding, a holiday weekend, or a work trip where alcohol and late nights are practically guaranteed? Starting one or two weeks earlier (or later) could shift those high-risk days outside your challenge window entirely.
The same logic works in reverse. If you need to finish before a specific date: say, before summer, a holiday, or a big life event, count back 75 days from your deadline and that is the latest you can start. The visual calendar above makes this easy to spot at a glance. A few days of strategic planning now could save you from restarting the entire challenge halfway through.

Tips on Completing your 75 Day challenges
- Start before you feel ready. Waiting for the “perfect” Monday or the first of the month is just procrastination in disguise. Use the calculator above to find a start date that avoids your biggest obstacles, then commit. The best time to start is the day you stop planning to start.
- Tackle your outdoor workout first thing in the morning. The outdoor session is the rule people dread most, especially in bad weather. Getting it done early means you cannot talk yourself out of it later. It also sets the tone for the rest of the day and makes your second workout feel like a bonus, not a burden.
- Prep your meals on Sunday. The number one reason people restart 75 Hard is a diet slip, not a missed workout. Spending an hour or two each week batch-cooking meals removes the daily decision fatigue that leads to ordering takeaway at 8pm. If your meals are already in the fridge, willpower barely enters the equation. Use one of our free meal planners to assist with this.
- Carry your water bottle everywhere. A gallon sounds like a lot until you break it down: four refills of a 1-litre bottle spread across the day. Fill it first thing in the morning and set a target to finish one bottle before each meal. By dinner, you only have one left.
- Stack your reading into a daily ritual. Ten pages takes roughly 15 to 20 minutes. Pair it with something you already do every day, like your morning coffee or the last 20 minutes before bed. Attaching the habit to an existing routine makes it far harder to skip.
- Track your progress on paper, not just in your head. A 2015 study by Dr. Gail Matthews at Dominican University of California found that people who wrote down their goals and tracked progress were 42% more likely to achieve them than those who simply thought about their goals. Writing creates a layer of accountability that mental notes cannot match. Print a daily 75 hard tracker (or 75 medium, 75 soft) and physically tick off each task as you complete it. The simple act of putting pen to paper reinforces your commitment and makes each completed day feel tangible. Pair it with a weight loss tracker if body composition is part of your goal, so you can see the trend line building over the full 75 days rather than fixating on daily fluctuations.
- Plan for your hardest days, not your easiest ones. Everyone can do Day 1. The challenge is Day 38, when it is raining, you are tired, and nobody would know if you skipped the outdoor walk. Decide now what your wet-weather workout looks like, what you will eat at restaurants, and how you will get your reading done on travel days. Having a plan for the worst days means you do not have to make decisions when your motivation is lowest.
- Tell someone what you are doing. Accountability is one of the strongest predictors of follow-through. You do not need to post daily updates on social media, but telling one person (a partner, friend, or training buddy) means someone will ask how it is going. That quiet expectation is often enough to keep you honest on the days you want to quit.
- Do not aim for perfection, aim for consistency. If you are doing 75 Soft or 75 Medium, a rough day is not a reason to abandon the whole challenge. Get back on track the next morning. Even on 75 Hard, where a missed task means a restart, treat every restart as proof that you are still in the fight. Most people who complete 75 Hard did not do it on their first attempt.
- Remember why you started. Write your reason down on Day 1 and put it somewhere you will see it every day. Not a vague goal like “get fit,” but something specific and personal. When the challenge gets hard (and it will), that reason is what pulls you through the final few weeks when motivation has long worn off and discipline is the only thing left.
When does 75 Hard end if I start today?
The 75 Hard challenge lasts exactly 75 days. Enter today’s date into the calculator above to see your exact completion date. The challenge runs for 10 weeks and 5 days.
What is the difference between 75 Hard, 75 Medium, and 75 Soft?
75 Hard requires two 45-minute workouts daily (one outdoors), strict diet with no alcohol, 1 gallon of water, 10 pages of nonfiction reading, and a daily progress photo. If you miss anything and you restart from Day 1. 75 Medium requires one workout, 90% diet adherence, and adds meditation. 75 Soft is the most flexible: one workout with a weekly rest day, moderate eating, and fiction books are allowed.
What happens if I miss a day on 75 Hard?
On the original 75 Hard challenge, missing any single daily task means you restart the entire 75-day challenge from Day 1. This is the core rule that makes it a mental toughness challenge. 75 Medium and 75 Soft have more forgiving failure rules.
How many workouts is 75 Hard in total?
75 Hard requires 150 total workouts over the challenge (two per day for 75 days), totaling 112.5 hours of exercise. 75 Medium and 75 Soft require 75 workouts each (one per day).
Does walking count as a workout for 75 Hard?
Yes, walking counts as one of your two daily 45-minute workouts on 75 Hard, as long as it is a full 45 minutes. Many people use walking as their outdoor workout. On 75 Soft, walking and yoga also count, and one recovery day per week is allowed.
What if I struggle to drink a gallon of water every day?
A gallon is roughly 3.8 litres or 128 fluid ounces. The most common strategy is to spread it across the day. Drink a large glass first thing in the morning, carry a marked water bottle, and set hourly reminders. On 75 Medium, the water target is half
your body weight in pounds converted to fluid ounces (for example, 80 kg / 176 lbs means 88 oz). On 75 Soft, the target is a more manageable 3 litres per day.
What if the 75 Hard Challenge feels too difficult for me?
Start with 75 Soft. It follows the same 75-day structure but with gentler rules – one workout per day with a rest day each week, flexible eating, social drinking is allowed, and there is no restart penalty if you miss a day. Once you complete 75 Soft,
you can step up to 75 Medium or the full 75 Hard with confidence. Use the challenge type dropdown in the calculator above to compare all three variants side by side.
What should I include in my diet plan for 75 Hard?
The 75 Hard rules do not prescribe a specific diet. You choose any structured eating plan aimed at physical improvement and stick to it with zero deviations for all 75 days. Popular choices include calorie counting, macro tracking, keto, whole foods, or simply cutting out processed food and sugar. The key rule is no cheat meals and no alcohol, full stop.
