Martina Sáblíková and Milan Sáblík are a rare example of sister and brother both holding world records in the same sport at the same time; Martina holds the (senior) world records in the 5000 m and 10,000 m events (both from March 2007) and in the 3000 m event (from March 2019), while Milan shared the junior world record for the team pursuit with fellow Czech junior skaters Pavel Kulma and Zdeněk Haselberger (from November 2007 till March 2010). Sáblíková has been successful despite there being no speed skating rinks in the Czech Republic. Because of this, Sáblíková's coach Petr Novák had to devise several unorthodox but successful training methods.
