English Despite the sometimes exciting events unfolding in the race for the World Cup title, biathlon still cannot become more popular than popular sports such as football, hockey and basketball. Bets on biathlon are not even available at every large and well-known bookmaker. Without a variety of choices, there can be no surebets.
So the answer to your question is that there are some biathlon surebets, but they are rare. Profits are impossible under these conditions.
