When last we posted about Jane Tomlinson's Ride Across America to raise breast cancer awareness and money for cancer research, she was having a difficult time.

In hip and back pain from recently finishing chemotherapy just two weeks before she left San Francisco -- final destination New York -- she began suffering dehydration and extreme fatigue near Cedar City. The diary entry for that day of the ride read, "All we need now is your good thoughts and a massive change of luck."

Tomlinson rallied with renewed energy, continued on, and yesterday she made it to the halfway point of her coast-to-coast ride.

I am following her journey with great enthusiasm because of her courage and strength. Six years ago, when she was diagnosed with terminal breast cancer, she was told she had six months to live. Not only has she outlived all predictions, she is also known as the only cancer patient to complete a full Ironman triathlon and the first person to run a marathon while on chemotherapy. During chemotherapy, I had trouble walking across the room or keeping jello down. Jane is incredible.
