Are all track fields and lanes the same length?

No, not all track fields and lanes are the same length. Standard outdoor tracks, for example, are typically 400 meters in circumference for the innermost lane, but the length of each lane increases slightly with each outer lane due to the curvature of the track. Indoor tracks may vary in size, often ranging from 200 to 300 meters per lap. Additionally, some tracks may have different configurations or purposes that affect their dimensions.
