ITTIGEN, Switzerland -- Switzerland's anti-doping agency wants British officials to explain why European champion Viktor Rothlin spent almost as much time giving blood before the London Marathon as he took to run the race.
Rothlin complained after finishing 11th on Sunday morning that his arms were sore after a two-hour blood sample session ended at 11 p.m. Saturday.
Anti-Doping Switzerland director Matthias Kamber told The Associated Press that U.K. Anti-Doping's work at Rothlin's hotel was "certainly not ideal."
The person collecting the sample "couldn't really take blood professionally," Kamber said.
"In my thinking, it's not acceptable," he said.
The test was expected to last 15 minutes, and Kamber said he told organizers before the test that it "shouldn't take too long."
Rothlin will likely break with protocol and announce the test results from the World Anti-Doping Agency-accredited laboratory in London next month because of the publicity.
"He has to do it," Kamber said.
Kamber said the Swiss agency requested the sample, which is meant to prevent athletes from doping in the final hours before a race.
"We have to act like this because the products used are in such small doses. It is working on the edge," he said.
Rothlin, who is one of Switzerland's best medal hopes at the 2012 London Olympics, completed the course in 2 hours, 12 minutes, 44 seconds. He was more than eight minutes behind Kenyan winner Emmanuel Mutai, and five minutes off his personal best.
The 36-year-old former world bronze medalist said his forearms were blue after the doping control.
"It was particularly unfortunate to happen at this moment because I had to get up at 5 a.m for the race," Rothlin said after completing his run in London.
