Any timed effort works
The challenge does not have to be a bike ride. If it has a start, a finish and a clock, it can carry a prediction board — and somebody in your club or charity is probably already planning one.
A sponsored ride
A marathon or a run
A long-distance swim
A summit or a hike
A 24-hour challenge
Three things to decide, then it runs itself
Set the window
Pick the effort, and the range the finish time will fall in. That range becomes a board of time slots. Predict the Ride ran from 06:00:00 to 09:00:00 in 30-second steps, which made 361 of them.
Supporters predict
Each supporter chooses the time they think the finish will come in at, and pays for the privilege. Every slot sells once and once only, so the board fills up and the good times go early.
Closest prediction wins
You record the official time afterwards, and the closest prediction without going over takes the prize. The winner is decided by judgement, not by a draw, and the whole board is a matter of public record.
The prediction board, filling up
Sold slots go navy, yours stands out in coral, and the closest one to the official time wins.

It is not a raffle, and that is the point
A raffle asks for a donation and hands back a random number. A prediction challenge asks your supporters what they think — and then makes them wait all day to find out.
One slot, one owner
A raffle can sell the same chance to a thousand people. Here each time can be taken only once, so a supporter owns their prediction outright — and a board that is filling up is its own reason to enter today rather than next week.
A fixed, visible ceiling
The board has a known size from the moment it opens. Supporters can see exactly how many predictions exist and how many are left, which keeps the odds honest and tells you precisely what a sold-out campaign is worth before you start.
Judgement, not luck
People who know the route, the rider and the weather can reason their way to a better answer. That turns an entry into a conversation, and a conversation is what gets shared.
It belongs to your community
The challenge is somebody your supporters already know, doing something hard. They are not buying a ticket — they are backing a person, and then waiting all day to see whether they called it right.
