Well, his hobbies included playing the violin, sword fighting, singlestick and boxing along with a mixture of some martial arts. In later times he became a beekeeper. That was definitely surprising to me!

Sherlock Holmes was a skilled violinist and was learned in the Oriental defense art of baritsu, which is actually a fictional martial art but related to judo, I believe. He was interested in chemistry, and frequently dabbled with poisons and acids and anything he needed to fulfill experiments. According to Dr. Watson, he was an excellent singlestick player (one-handed fencing stick), boxer, and swordsman. He also spoke French quite a lot in his sentences, so odds are he was able to speak it fluently. Then there is the obvious interest in crime and sensational happenings.

Sherlock Holmes enjoys fencing, talented at fencing but most of all, he loves the violin as well as music itself and to test out new chemical experiments. According to him, his mind starves for things to think and to do.

Some sports that were around 100 years ago but do not exist today include tug of war as an Olympic sport, singlestick fencing, and roque (a variation of croquet). These sports have either faded in popularity or have been replaced by more modern alternatives.
