World-class sportswomen combining motherhood with incredible athletic achievement. Kim Chakanetsa asks how they do it, what support they have behind the scenes, and what it means to them to be both a mother and a top athlete.

Jasmin Paris is a record-breaking British ultrarunner and the first woman to win the infamous Spine Race, a winter marathon along the UK's Pennine Way which is widely regarded as one of the world's toughest endurance races. At the time Jasmin was still breastfeeding her baby daughter, and she had to express milk along the way. And that's not the only demand on her time - she also works full-time as a vet at the University of Edinburgh.

Nicola Spirig is a 37-year-old professional Swiss triathlete, who gave birth to her third child in April this year, and was back competing just a few weeks later. Nicola won the gold medal in triathlon at the London 2012 Olympics, and came back after having her first child to win silver in Rio de Janeiro in 2016. Now she's aiming for Tokyo 2020. She says she couldn't do it without the support of her husband, who does the bulk of the childcare.
