Setting up a challenge takes a couple of minutes, and almost all of it is easy. The name is fun to pick. The dates are obvious. Then you reach the goal field, type a number that feels about right, and move on.
That number does more work than any other part of the setup. Set it too high and people quietly stop logging around week two, because the target has already drifted out of reach and there is no reason to keep score. Set it too low and nobody feels much of anything when they pass it. Get it right and almost everyone finishes, earns their medal, and asks when the next one starts.
Here is how to pick it deliberately.
First, know what the goal actually means
On Miles With Friends, the goal is a target for each person individually. It is not a total for the whole group added together.
If you set the goal to 30 miles, then every walker in your challenge is aiming for their own 30 miles, and everyone who reaches it earns a goal medal. Ten people can hit it. Everyone can hit it. Nobody has to come first, and nobody takes a medal away from anyone else.
Plenty of groups do start with a team number in mind, though, and there are two good ways to handle that. The simplest is to divide your team total by the number of people taking part and set that as the goal. A group of five chasing 150 miles together would set 30, so everyone has their own share to reach and everyone who reaches it earns a medal.
The other option is to set the full team number as the goal and treat it as the group's shared aspiration. That suits a destination-style challenge, where the fun is watching a big number come down together. Just bear in mind that the goal medal appears when someone reaches that number on their own, so with a large team total most walkers will finish the challenge without one.
Start from what people already do
The most common way to get this wrong is to set the goal from your best self rather than your normal self. You picture the version of you who walks every single day, and you build the target around that person. Your friends do the same thing. Then real life arrives with a busy week, a cold, and a rainy weekend, and the number that felt inspiring on day one just looks like a reminder that everyone is behind.
So work from the walking that is already happening. A useful reference point: a relaxed neighborhood loop is usually somewhere around a mile, a decent walk is two to three, and thirty minutes at an easy pace lands near a mile and a half. If your group already walks a few times a week without thinking about it, that is your foundation.
One more thing worth doing: aim at your least active friend, not your most active one. Your fittest friend will sail past whatever number you choose and enjoy themselves regardless. The person on the edge of joining is the one the goal actually speaks to, and they are the one most likely to quit if it looks impossible in week one.
A simple way to get the number
You do not need to be precise. You need to be roughly right and slightly conservative. Multiply three things, then take a little off the top:
miles in a typical walk × walks per week × weeks in the challenge, then subtract about 20 percent.
That last step is the important one. The 20 percent is real life: the week someone travels, the stretch of bad weather, the days that just do not happen. Almost every goal that fails was calculated as though every week would go perfectly.
2 × 3 × 4 = 24 miles. Take off 20 percent and round to something friendly: set the goal at 20.
3 × 4 × 4 = 48 miles. Take off 20 percent and round: set the goal at 40.
Suggested starting targets
If you would rather skip the arithmetic, these are reasonable places to begin for a one-month challenge. They are starting points, not rules, and you know your group better than any table does.
| Your group | Goal per person, one month |
|---|---|
| First-timers, or a wide mix of ages and fitness levels | 15 to 20 miles |
| Casual walkers who get out a few times a week | 20 to 30 miles |
| Regular walkers, most days of the week | 30 to 45 miles |
| Runners and very active groups | 50 to 75 miles |
| Community, workplace, school or Scout groups | 15 to 20 miles |
That last row is deliberately low. A community or youth group spans a much wider range of ages and abilities than a group of friends who already walk together, and the goal needs to be reachable for the person at the quiet end of that range, not the athlete at the front.
For a shorter challenge, scale it down rather than reaching for a new number. A two-week challenge wants roughly half the monthly figure, and a one-week sprint about a quarter.
When in doubt, set it too low
The two mistakes are not equal, and it is worth understanding why.
A goal that turns out too easy costs you very little. People pass it, feel good, collect their medal, and usually keep logging anyway because by then the habit has taken hold. Several will quietly push past it just to see how far they get.
A goal that turns out too hard costs you the whole challenge. Once the target is visibly out of reach, logging stops meaning anything, and people do not just miss the goal, they stop opening the app. That is how a challenge dies in week two with everyone still technically enrolled.
Since every single person who reaches the target earns a medal, a slightly generous goal ends your month with a board full of medals and a group that wants to do it again. That is worth far more than the satisfaction of having set a demanding number.
You can change it later
The goal is not locked in when you create the event. You can edit your challenge and adjust the number at any point, which takes most of the pressure out of this decision.
Raising it mid-challenge works well when the group is running away with it. If half your walkers hit the target in the first ten days, moving it up gives everyone a fresh thing to chase, and it feels like a celebration rather than a change of rules. Announce it, and make it sound like the group earned it, because they did.
Lowering it is more delicate but sometimes the right call. If it is clear by the halfway mark that almost nobody will finish, a quieter target is far better than watching everyone drift away. Frame it around the group rather than the number: something like "shifting our goal to 20 so we all finish this together" lands much better than an unexplained edit.
Signs you set it wrong
You will usually know within the first ten days. Watch for these:
- Logging drops off sharply after the first week. The most common symptom of a goal that is too high. People do the mental arithmetic, see they are already behind, and stop.
- Several people hit the target almost immediately. Too low. Not a disaster, but you are leaving momentum on the table, so raise it and give them something to chase.
- The quieter half never logs at all. Often the target looked intimidating from the outside. Worth a friendly message making clear that any distance counts, and worth considering a lower number.
- Nobody mentions the goal. If it never comes up in the group chat, it is not doing its job. A goal people talk about is one that is close enough to matter.
If people joined but never got started at all, the goal may not be the real problem. Why Most Friend Fitness Challenges Fizzle in the First Week covers the other reasons that happens.
Frequently asked questions
Is the goal per person or for the whole group?
Per person. Everyone in the challenge is aiming at the same number individually, and everyone who reaches it earns a goal medal. If you have a team total in mind, divide it by the number of people taking part and use that figure as the goal.
Do I have to set a goal at all?
No, it is optional. A challenge works without one, and people will still log miles and appear on the leaderboard. But a goal is what turns a shared log into a challenge, and without one there is no medal for anyone to earn.
Can I change the goal after the challenge starts?
Yes. You can edit your event and adjust the goal at any time. Just tell the group when you do, so it reads as a deliberate decision rather than a surprise.
What if my friends are at very different fitness levels?
Set the goal for the less active end of your group. Your most active friends will pass it comfortably and keep going for their own reasons, while a number pitched at them would quietly shut everyone else out. A goal that everybody can reach is what keeps a mixed group together.
Do miles from running, cycling or swimming count toward the goal?
Yes. Miles are miles on Miles With Friends, whatever activity produced them, so a mixed group of walkers, runners and cyclists can all chase the same target. Bear in mind that cycling covers ground much faster than walking, so if your group is genuinely mixed, set the target with your walkers in mind.
