It meant she would be able to work in a bunch, but then lost them when the shift change happened and fresh legs took over.
Wearing the lucky horseshoe belly button ring her mother had gifted her, Giddens was determined to keep going for Mother's Day.
Another big help was Wanganui's Colin Wright, father of leading triathlete James, who rode with her as she tired when the day rolled on.
"I was in too much pain to be bored." Giddens was also able to put off using her asthma inhaler until the 190km mark, having worked out the best inhaler for her condition.
With a new trophy, Giddens will depart to rejoin her team in Wisconsin tomorrow.
One of her first races of the season is also one of her favourites - Iowa's Snake Alley Criterium, which includes racing up an 84m alley once named by Ripley's Believe It Or Not as the most crooked alley in the world.
