大阪府 大阪市
Flat
A large city race with little elevation change, but the field is big enough that the opening kilometres are hard to run at your own pace. Where you start affects how much time you lose early, so be honest on your predicted-time declaration.
Observed at Osaka on the same date over the past 5 years
A good temperature range for chasing a personal best. Avoid overdressing.
