Inspirational fundraiser and terminal cancer patient Jane Tomlinson was battling with strong side winds yesterday as she passed the 2,000-mile mark on her Ride Across America, her husband said.
The mother-of-three opted to continue after talks with husband Mike over whether it was too dangerous.
The 42-year-old, of Roth-well, Leeds, cycled past 2,000miles as she rode into Salina in eastern Kansas yesterday after 200 hours in the saddle since she left San Francisco's Golden Gate Bridge on June 29.
Mrs Tomlinson and her two co-riders are determined to complete the 4,200-mile journey to New York by September 1.
Mr Tomlinson, 45, said: "This week they've been buffeted by huge side winds which has made the cycling hazardous. We had a discussion on Sunday as to whether to continue. Jane made the decision.
"She's not prepared to get to New York later than September 1. She's decided she would rather stop than finish late.
"So she's set a target of getting to Kansas City by Sunday. There was due to be a rest on Tuesday and that was cancelled so they could have a push to reach the target otherwise the ride will be over.
"If she gets to Kansas she will have ridden ten days without a break. Her legs are tired are she's very fatigued but we either get to New York on September 1 or not at all."
Since being diagnosed with advanced metastatic breast cancer, Mrs Tomlinson has become the only cancer patient to complete a full Ironman triathlon and the first person to run a marathon on chemotherapy.
She also did a 2,500-mile bike ride, from Rome to home.
