Watch Matthew Hudson's full report
The Boat Race being held near Ely on Sunday is a closed event. People who turn up and try to watch it live risk a £200 fine.
However, there are a handful of local people who unexpectedly find themselves with ringside seats, because they own homes along the riverside.
Becky and Dave's riverside home in Littleport gives them a magnificent view of the finishing line for the historic boat race between Oxford and Cambridge University.
They've been watching the Cambridge team train on the river for months now.
When Robin Edwards retired four years ago he had no idea his new home would become the equivalent of a Royal Box for one day only.
What makes people like Becky, Dave and Robin even more fortunate is that practically nobody else can watch the live event.
Concerns over large crowds gathering during the pandemic means roads and footpaths will be closed. Anyone trying to sneak a peek risks a £200 fine.
Covid marshals and environment agency staff will be out and about on Sunday dissuading people from trying to watch the race live.
All approaches to the course will be shut and patrolled from noon on Sunday.
The police say travelling here and trying to watch the race live will be a waste of time.
The last time the race was held away from the Thames was in 1944 during the Second World War, and it was held in Ely that year.
Empty river banks are unlikely to effect the efforts of the crews from Cambridge and Oxford.
They'll know millions of us will be willing them on from the comfort of our homes - as we do every year.
