The exhausted cyclist rolled into Griffith to see his kids on Saturday after smashing the last legs of the Great Cycle Challenge to raise money to “kick cancer’s butt”.

He spent the month of October pedalling furiously to meet his personal goal of 1600 kilometres, but he ended up riding 1826km instead - all while juggling his day job.

The 53-year-old dragged himself out of bed at 4am every morning, donned his lycra, and hit the road for at least 60km before he went to work.

“It can be tiring getting up early every day, but it wasn’t too bad,” Mr McLean said.

The lycra-clad dad said the gruelling regime was well worth it, because he managed to raise over $1000 for the Children’s Medical Research Institute.

“I’ve got a few friends and work colleagues who’ve had cancer, but I’m lucky to have three healthy kids,” he said.

One of his sponsors was Baker’s Delight, who motivated Mr McLean by promising to donate $1 for every kilometre he cycled over 1000km.

By the end of the ordeal Mr McLean had improved his fitness quite a bit, and he even lost a total of six kilograms of body fat.

The lean keen cycling machine said he was now looking forward to seeing his kids in Griffith and resting his powerful thighs.

Looking back he said it was a comfortable ride with no chafing, which he attributed to his tight-fitting lycra cycling suit.
