I’d watch only cause it’d be a train-wreck.
The second exchange requires the full distance to generate the demands of the exchange. The incoming runner must enter the curve on the outside of the outgoing runner, and this disadvantage makes fatigue a huge issue if the pass isn’t made cleanly at the first opportunity. The incoming runners at the first and third exchange can take advantage of their inner lane position to cut the distance to their teammate if they need a second chance.
Bottom line: All exchanges require curve work at the appropriate spot.
