London Marathon sets a new world record for the number of finishers in spite of hot conditions for its 45th edition.

Sabastian Sawe used smart tactics to pull away for the men's title in the London Marathon, while Tigst Assefa smashed the women’s-only world record.

Assefa finished in an unofficial time of 2 hours, 15 minutes and 50 seconds, the fastest ever in a women's-only marathon — but 25 seconds slower than the course record set by Paula Radcliffe in 2003 when it was a mixed race.
