"They were working up until dark basically, they were on a mission to reopen the track," Ms Osborne said.
DoC expects at least 4000 people to do the full Mangapurua and M2C Track this summer and more than 10,000 people to do parts of the track.
Among those who took up the challenge of riding the newly cleared track was a woman from Wanaka, who celebrated her 71st birthday on the track with family.
"The Mangapurua and M2C Track is a definite asset to the Whanganui region given the large and growing number of keen cyclists ready and willing for the challenge," said DoC recreation ranger Dave Westcott.
DoC would also like to remind people to remain aware of fire risks this summer.
