The vision over Lake Burley Griffin on Sunday was limited due to heavy morning fog.
But for the masses of people walking or running around its shores, their vision of raising vital funds for breast cancer research could not have been clearer.
More than 4000 people gave up their Sunday morning sleep in on a chilly Canberra morning to take part in the Mother's Day classic.
A sea of pink was seen around the lake as people walked or ran around the five and 10 kilometre course, many with prams or their dogs in tow.
Now in its 22nd year, the Canberra run was one of 88 similar events across the country, with an estimated 100,000 participants nationally.
As well a chance to raise money for breast cancer research and support projects, the event was an opportunity to remember family members and friends who have died from cancer.
Canberran Rebecca Kelly was at the event alongside a group of more than 20 family and friends.
The group were taking part to remember Ms Kelly's sister Rachel, who died of breast cancer last year.
"This is our first Mother's Day without her," Ms Kelly said.
"We do the Mother's Day Classic every year, and it's even more significant this year."
The group were all in matching T-shirts saying 'Doing It For Rachel'.
The group also included Rachel's husband and two children, and Ms Kelly said it was an emotional day for them all.
"[Rachel] was so full of life, and it means everything because she was always here with us," she said.
"She was such a good mum, and she was taken just too young."
The start of the day saw a minute's silence for victims of breast cancer.
Survivors were also honoured with a special wave of walkers around the lake, made up of those who had previously been diagnosed with breast cancer.
This year the event aimed to raise more than $2.1 million for the National Breast Cancer Foundation.
Jean Coddington was among the runners who took part in the 10 kilometre run, alongside her daughter Katrina Morris.
Ms Coddington said she had been running with her daughter at the event for several years.
"We've been coming here for a number of years," she said.
"I had a couple of girlfriends lost to cancer, and it's a morning to remember them and to spend the morning with my daughter."
Ms Morris said she ran with her mum several times throughout the week, and events like the Mother's Day classic strengthened the bond even further.
"I think it's really special.There's not that many people out there that would do a 10 kilometre run with your mum," Ms Morris said.
