Ms Rasmusen said when the team began training last year, many had never touched a rowing machine before.
"I've never rowed before - and honestly, if I can do it, anyone can. It's great for fitness and really great for team building. It's hard work but we're having a lot of fun."
Each day has a different theme. Tuesday's theme was Hawaiian, so the participants were rowing in brightly patterned shirts and lei.
The team's youngest rower is 28; the oldest is 64.
The team began at midnight on Sunday and Ms Rasmusen said while they were expecting to finish on Friday, they are well ahead of schedule and should finish on Thursday.
Ms Rasmusen said anyone was welcome to stop in for a coffee and to support the women.
