完走 and 走行: a finished race, a finishing goal, and driving
Read marathon completion and a goal set at the start alongside prototype driving and rainy-day visibility.
完走: a completed race and a goal at the start
完走 (かんそう) means completion of a race. 「初めての市民マラソンを自分のペースで完走した。」 means “I completed my first community marathon at my own pace.” Completion of the first community marathon at the speaker's own pace is explicit, without a placing or time.
「順位よりも完走することを目標にして走り始めた。」 means “I began running with the goal of finishing rather than placing.” Finishing rather than placing was the goal when running began.
走行: a driven prototype and visibility during travel
走行 (そうこう) means driving or travel. 「試作車を専用の道路で走行させた。」 means “We drove the prototype vehicle on a dedicated road.” 走行させた describes having the prototype driven on a dedicated road.
「雨の日は走行中の視界が悪くなりやすい。」 means “Visibility while driving tends to be poor on rainy days.” 悪くなりやすい expresses a tendency for poor visibility during driving on rainy days.
Separate endpoint completion from starting
完走した reports completion; 完走することを目標にして places completion inside a goal.
Driving the vehicle or describing visibility during travel does not establish arrival at every route's endpoint.
Does starting to run with 完走 as the goal establish a completed race?
Show the answer and why
No. Only the goal and start are reported. The separate first-marathon example with 完走した explicitly reports completion.
