Louise Clark says she committed to the challenge last Sunday — to coincide with Bowel Cancer Awareness Month — after one of her best friends from university in the UK died from the disease in February.
"She was 41 and I turn 41 in a couple of weeks’ time."
Clark left a container at the bottom of Tobins for supplies, but also with a QR code on it for people to donate.
"The amount of strangers that saw me and who donated, I was just blown away by the support, it was incredible."
She says she chose a challenge that was accessible, and as result, she had friends along with her husband and daughter join her for various laps.
Over 12 hours she completed 11-and-a-half laps, or 51.79km, with an elevation gain of 2811m, and the day after was feeling it in her hips.
A highlight was seeing a rainbow after rain in the afternoon — "rainbows remind me of my friend, so I was like, ‘this is amazing"’.
As of Monday she’d raised $2695, including a matching contribution from toilet tissue manufacturer CottonSofts.
Her link — shorturl.at/hJkFa — is live till the end of the month.
