[/quote] if an event were to be conducted by time, rather than by distance, then this should solve the problem if i understand your question correctly.

this could also work, i think it would have to be non drafting, and finish place maybe based on points, as aggregating run and bike distance is apples and oranges

now that i think about it more, this maybe the easiest option with current zwift programming. do 15 min R1 and assign points to the finish times. could be done with or without categories . bike could be a 30 minute race set to start exactly 20 min after R1. same thing with points assigned to finish place with or without categories... R2 would then start 35 min after bike, and also be a fixed time, whoever runs farthest gets most points etc. total final points determines winner..... is that what you were thinking?
