1. The Epsom Derby, Britain's most famous horse race 2.5 min

   Workforce's 2010 record run covered the mile and a half at over 56 km/h — and the race has been run every year since 1780, even through both World Wars.

2. Yuri Gagarin's entire Vostok 1 spaceflight 108 min

   The first human spaceflight was a single orbit — and Gagarin ejected and parachuted down separately from his capsule, landing in a potato field.

3. The Isner-Mahut match, the longest in tennis history 11.1 h

   The 2010 Wimbledon first-rounder stretched over three days with a 70-68 final set — the scoreboard wasn't programmed to go that high and broke.

4. Holi, the Hindu festival of colours 2 days

   It opens with the Holika bonfire at night and erupts into colour-throwing the next day — the powders were traditionally made from flowers and herbs.

5. The Romanov dynasty's rule over Russia 304 years

   It began with a 16-year-old reluctantly accepting the throne in 1613 and ended 304 years later with Nicholas II's abdication in 1917.

6. How long the Hagia Sophia has been standing 1.5K years

   Built in just five years under Justinian, it has since served as cathedral, mosque, museum, and mosque again across nearly 1,500 years.
