hypothesis: These three cyclists are bitter rivals.
explanation_1: Cyclists are at the starting line. This does not imply that they are bitter rivals.
explanation_2: Indoor track cyclists doesn't imply they are bitter rivals.
explanation_3: The first sentence doesn't indicate any relationship between the cyclists other than them all being at the starting line. Maybe they are bitter rivals or maybe they are complete strangers to each other.
