Luke Campbell probably thought getting into the boxing ring for this summer's Olympics would be the most difficult challenge of the year, until he delivered his own son.
The bantamweight boxer, who scooped gold at this year's Olympics, had to help deliver his new son Lincoln after his partner went into labour at their home in Hull.
Luke and his other-half Lynsey Kraanen had been planning a home birth but the couple soon realised that the emergency services would not arrive in time to help out, so it was down to Luke and Lynsey's dad Charlie to deliver the little boy.
Speaking to the Sun, Luke said: "I wasn't scared before my Olympic final, but when we realised the baby was coming and we had no midwife or professional help, that was scary.
"Lynsey did incredibly well, she had no pain relief. I've had a few knocks in the ring but this was another level. Luckily everyone's fine."
He added that the baby was so quick to arrive that they did not even have the time to blow up the birthing pool and fill it with water.
Lincoln is the second baby for the couple who are also proud parents to toddler Leo.
If Luke had been previously unknown except in sporting circles, he will be a household name soon enough as he has signed up to take part in the new series of Dancing on Ice.
He is partnered with professional skater Jenna Harrison.
