“It can’t possibly work!” The idea behind a double funnel is to maximise the workable space between the finish line and finish tokens. One thing we cannot manipulate is time. As an event grows larger in size more people will cross the finish line at the same time. This Saturday’s event, which saw a total of 731 individuals cross the line, was our third busiest event.
On Saturday, there were a total of 65 people who crossed the finish line between 27:00 and 27:59 minutes. That’s more people than attended the first two Woodhouse Moor parkruns, COMBINED. In fact, approximately half of all the participants at Woodhouse Moor on Saturday crossed the line between 24:00 and 31:59. That’s 362 parkrunners in just eight minutes! Even if we make the assumption that a zealous volunteer can hand out a finish token every two seconds it would still take 12 minutes to do so. That’s providing they don’t develop repetitive strain injury in the meantime. In those additional four minutes we would have seen another 129 people cross the line.
The maths tells us that we’re reaching a point at our event where we’re a victim of our own success - we have more people crossing the line than we can handle. The double funnel is a useful way of negating that fact.
The double funnel effectively doubles the space we have to play with, allowing us to ‘hold’ parkrunners in position, yet offset them from the main funnel. The funnel will flow as normal until it reaches ‘critical mass’, and the risk of parkrunners backing up over the finish line starts to increase.
At this point, our funnel manager (aka Count Spatula) will make the call to split the queue. The last person of the queue is given a spatula and the new line is formed, adjacent to the current one. At the end, stood just by finish tokens, is another funnel manager who is keeping a close eye on the spatulas. When spatula A is handed over, the funnel manager at finish tokens now knows that the second queue can start to flow. This second queue of people will continue to flow until they see another spatula, spatula B, denoting the end of that bunch of parkrunners. At this point, that queue will be held and the original funnel will flow, until the next spatula is reached, and on it goes…
