from the documentation:
update_record should not be confused with
>>> row.update(name='Curt')
because for a single row, the method update updates the row object but not
the database record, as in the case of update_record
so you should use update_record instead. or even better:
db(db.contest.id == id ).update(running = value)
which only results in one sql statement.
