The very top university men will be in Hachioji, but most of the rest will be at Kanagawa's Keio University for the Kanto Region University Time Trials. Additional overflow will head to Saitama for the Heisei Kokusai University Time Trials. Among them is David Nilsson (Sweden), who set a Swedish national record of 1:02:09 at last weekend's Ageo City Half Marathon. Nilsson had hoped to run in Hachioji, but following the Bowerman Track Club's Chris Derrick and Andrew Bumbalough running Hachioji two years ago and Australia's Harry Summers last year, organizers made it their official policy this year to prohibit non-Japan-based athletes from entering. Considering Hachioji's stature as an event on the world calendar and principal sponsor Konica Minolta's position as a major international brand it's a highly regrettable stance to have taken.
