Indoor triathlons use stationary bikes but how is this fair since they don't take into account the load one would be hauling like a normal bike. For example if someone 100 lbs and someone 200 lbs both generated the same amount of power/output they would have the same distance on a stationary bike whereas on a real bike the 100 pounder would go much further. How does this work also does everyone have the bike set to an identical resistance level? Lastly some indoor triathlons just give you say 30 minutes in each discipline and then calculate total milage this seems incredibly unfair to good swimmers. If you are twice as good as me at swimming and swim 1 mile in the 30 mins and I only swim .5 miles but in biking I am twice as good and bike 16 miles to your 8 miles our total distances would be 16.5 miles to 9 miles. This system seems to heavily reward those who excel at cycling.
