Comeback
Bloch retired in 2004 to start a family. She competed in the 2013 Maccabiah Games, winning a silver medal in the women's triathlon. She began competing again in cycling in 2014, after suddenly feeling a desire to return to the competition and adrenaline that attends cycling. In 2014, she won silver medals in both the Israel National Championships Women's Road Race and in the Israel National Championships Time Trials, both behind Israeli Paz Bash. She rode at the 2014 UCI Road World Championships, in and around Ponferrada, Spain. She did not finish, along with dozens of other riders who fell victim to a series of crashes, including a mass crash. In March 2016 Bloch won the Masada-Arad race in 52:01, came in second in the Dead Sea-Scorpion Pass race, eight seconds behind the 2:30:05 winning time of Antri Christoforou of Cyprus, and came in third in the Arad-Dimona-Arad race, behind Christoforou and Bash. In April 2016 she won the Crit on The Campuscriterium around Stirling University in Stirling, Scotland, ahead of Charline Joiner of Scotland. In June 2016 she finished second at the Scottish Road Race Championship, second at the Israeli Championships Women's Time Trial, and fourth at the Israeli Championships Women's Road Race. In the summer of 2016, she was ranked 88th in the world in the Union Cycliste Internationale world rankings, which qualified her to compete in the 2016 Olympics. Bloch represented Israel at the 2016 Summer Olympics in the Women’s Road Race in Rio de Janeiro, two years after returning to competition. At the age of 37, she was the oldest member among the 47 athletes on Team Israel. She finished the 141 kilometer road race in a time of 4:02.59, in 48th place among 68 riders. She was the first Israeli of either gender to compete as a cyclist at the Olympic Games since Henry Ohayon and Itzhak Ben David in 1960 in Rome.
