Two fathers from Scotland have advised caution to parents about the potential risks attached to school sports days.
Scott Hollas and Prof Donald Bloxham's participation at their children's school event took a bad turn as they ended up having to go to the hospital, as reported by the BBC.
Scott, 49, was having an energetic day running in the dads' race, but he was soon rushed to the A&E, where doctors told him that he had torn the ligaments in his leg.
Meanwhile, Donald suffered a similar fate as he tried to replicate his previous victory at his daughter's beach sports day, but this resulted in him collapsing three times on his way home.
The fathers spoke to the publication about their blunders, with Scott revealing that while he took a tumble - which was captured on camera - he persevered by limping to the finishing line.
He then explained how he felt immense pain in his knee after the race, stating that it started "getting really sore and I honestly thought it was going to explode," adding, "The skin just kept rising. My wife took me to A&E at the Belford hospital and I fainted three times with the pain.
"They had me on gas and air to calm me down. I had severely torn ligaments right down my leg and I was off work for a week," he continued. "So, dads' race - terrible idea."
On the other hand, Donald was confident that he would defeat the other fathers by replicating a race he did six years ago, but this failed as, after the sprint, his hamstrings began to hurt.
"I had this memory of victory at my daughters' nursery school sports day six years before and I thought I could replicate this in front of a larger crowd," he said. "I was ignoring the fact that I hadn't broken into a run for about five years, and ignoring the fact that my shoes had no grip and that I hadn't done any warm-up or stretching at all.
"I ambitiously broke into a sprint, then that leg twanged and the other leg twanged and I knew something had gone seriously wrong with my hamstrings," he added.
The dad said that there was "massive pressure" in the situation and that overall, the incident was a "rather embarrassing performance which I'm doing my hardest to wipe from memory".
Jojo Fraser - a mom and member of the Bad Parents' Club radio panel - is now calling on parents to still get involved in their children's activities.
"There are the ones with full-on activewear - the proper running shoes, and they mean business, the full gear," she said. "Then you have those in suits who're at their desk a lot and it's quite a lot for them to be running and they're quite nervous.
"And then you have the hippy people who've got their crystals in their pockets and their Crocs on and they're just going with the flow, seeing what happens," Fraser added.
However, Scott revealed that he is happy to hang up his trainers. In addition to his own fall, about "four or five adults" got hurt which is why his child's school is taking the initiative to change the rules from a running race to the egg and spoon or the sack race.
He also said that he will never be able to live the down his last sprint, noting that the video comes up every year on Facebook, and "every year everyone has a laugh at work or school".
But Scott concluded: "I don't mind - everyone has a laugh about it and so do I."
