In the past few years, many of track and field's greatest stars have proven that you can take time off to have a baby and return to the track in supreme form.
Just last year at the World Championships in Doha, many of us witnessed and were inspired by the mothers who continued to break down the barriers in sport while fighting for equality.
This Mother's Day, we've taken a look at four of track and field's most inspiring 'supermums' who raised their game after giving birth.
Allyson Felix
Less than a year after giving birth, Felix returned to the world stage in style last year in Doha. The American sprinter became the most decorated track and field athlete in World Championships history, eclipsing Usain Bolt's previous record of 11 gold medals.
However, Felix is bigger than just a track and field legend. In 2019, Felix challenged Nike's maternity contract that saw pregnant athletes financially penalised for having a child.
Since then, Nike amended its maternity policy to support pregnant athletes however, Felix decided against renewing her contract as she joined women's athletic-wear company Athleta.
Shelly-Ann Fraser-Pryce
Otherwise known as "Mommy Rocket", Fraser-Pryce continues to re-write history in spectacular fashion.
After winning the 100-metre title last year at the World Championships in Doha for the fourth time in her career, Fraser-Pryce completed a victory lap with her son by her hip - an image that defines what it means to be a supermum.
Jessica Ennis-Hill
In 2015, Ennis-Hill was crowned World Champion in the heptathlon in Beijing, just 13 months after giving birth.
A year later, Ennis-Hill found herself on the podium once again though this time, in silver medal position - narrowly missing out on gold in an impressive Olympic title defence in Rio.
Since retiring, Ennis-Hill founded fitness app 'Jennis' to inspire mothers to maintain fitness during their pregnancy.
Nia Ali
Mother of two and two-time world indoor champion Ali, claimed her first-ever World Championship gold last year in Doha over the 100-metre hurdles.
Prior to this, Ali claimed a silver medal at the Rio Olympic Games in an iconic American one-two. Ali's performances after giving birth prove that you can take time off to have babies and come back even stronger!
