On April 19, 2025, which country hosted the world’s first half-marathon in…

Concept

A dated current-affairs claim should be identified by matching three anchors across reliable reports: the date, the venue, and the claimed first-of-its-kind feature.

The host city then determines the country; unrelated national associations with robotics are not sufficient evidence.

Application

1. Reports dated April 19, 2025 describe the Beijing E-Town event as the world’s first half-marathon in which humanoid robots raced alongside human runners.

2. Beijing is the capital of China, so the host country identified by the venue is China.

3. The event description and date refer to one specific Beijing race, so the other listed countries do not fit the venue evidence.

Cross-check and contrast

• China contains Beijing, the city named as the race venue in the reports.

• Indonesia’s capital is Jakarta, not the reported venue.

• Japan’s capital is Tokyo, not the reported venue.

• Brazil’s capital is Brasília, not the reported venue.

Result

Therefore, the country was China.
