Following a report by the Sunday Times in August that revealed a database of suspicious blood tests in track and field, the four-time Olympian for Great Britain spent much of the year defending her career and records from speculation—even though she was not named in the article and she has never failed a drug test.
In January, the World Anti-Doping Association (WADA) announced that data in the leaked Sunday Times document was incomplete, and that the International Association of Athletics Federation (IAAF) followed proper procedures in researching questionable test results.
Still, this was all amid a controversial 2015 for running, in which a state-sponsored doping program in Russia was uncovered and lead officials at the IAAF—the sport’s governing body—were found to be blackmailing athletes, allowing them to avoid testing and hide positive test results.
Before that WADA announcement, Radcliffe sat down with Runner’s World Editor-in-Chief David Willey at the Walt Disney World Marathon Weekend in Orlando, where she took part in the 10K and half marathon. Radcliffe talked about how doping has hurt the sport and how she’s dealt with allegations regarding her blood samples.

The Kinvara has long been a workhorse in our stables. A year ago, the high-performing trainer won our Best Update award--mostly because of an upgrade to its midsole foam. This year, Saucony further improved the package. The outsole got a little extra rubber for increased durability--especially at toe-off and along the outer edge through the midfoot. The upper has a more secure fit thanks to a new saddle feature called "Pro-Lock," a triangular piece sandwiched between mesh in the midfoot that connects to the laces and pulls the upper snug against your foot. The upper fabrics also received an upgrade: A more durable mesh has been added in the forefoot, while a softer, more padded fabric now lines the collar.
