Today the RAGBRAI began.

RAGBRAI, an acronym for The Register's Annual Great Bicycle Ride Across Iowa, is an annual seven-day 472 mile bicycle ride across the state of Iowa. The ride began 33 years ago as a challenge made by one Des Moines Register newspaper journalist to another -- when John Karras, feature writer/copy editor suggested to Don Kaul, Over The Coffee columnist, that he ride his bicycle across Iowa and write columns about what he saw from that perspective.

Today, RAGBRAI has the distinction of being the longest, largest and oldest touring bicycle ride in the world. The ride is so popular that riders who wish to participate are required to enter a lottery for a spot in RAGBRAI.

Lance Armstrong will join RAGBRAI this year. Armstrong is participating in the ride to continue to raise awareness about cancer issues, the need for increased federal funding of cancer research and cancer survivorship. Armstrong sees Iowa as a pivotal place politically, and he is hoping to encourage locals to grill prospective presidential candidates on their positions on cancer research funding when they come to court Iowa voters.

Armstrong is more than concerned that for the first time in 35 years, the federal budget for cancer research has been reduced. He is single-focused about cancer survivorship, and remains consistently determined to fight for the best in cancer care and cancer cure.

When I was going through cancer treatment, I read Armstrong's book, It's Not About the Bike: My Journey Back to Life, in which he shared the philosophy of a cancer survivor's obligation of the cured. I was inspired to my own commitment and obligation in cancer survivorship. He has steadfastly lived up to his obligation. RAGBRAI is one more effort made -- and for a seven-time Tour de France champion -- a passion.
