To reach 8848m vertical metres, Mr Noble biked up and down the Skyline access road 21 and a-half times, which took him 22 hours.
He raised more than $6500 for inclusive tourism provider Makingtrax, to help it buy a gravity quad — a four-wheel, downhill mountain bike.
On Thursday, Mr Noble said he was "pretty tired" but had been awake by 6.30am.
Physically he was feeling "quite good" other than a sore knee and tender muscles.
Makingtrax founder Jezza Williams said Mr Noble’s effort was "very touching".
"The awareness it got and [which] we’re getting ... it’s unbelievable to have the support of not only Simon but his whole crew, the mountain bike club and Skyline."
Mr Noble’s Givealittle page — "The Longest Long Day" — will remain open until the end of the year.
