Sorry, cannot agree with you on this comment. The sport is designed the way it is and drafting is not as big of issue as people make it out to be. More officials would break up the remaining groups, but I like it just the way it is.
I remember back in the 80s when they played with the order of events, and none of the orders worked. Especially, trying to control bikes coming through finishing shoots.
Drafting is not an issue? It's the major issue! 50 athletes getting off the bike together is a joke. That's why I rarely watch it anymore. The original triathlons of the seventies were swim, run, bike but it wasn't till IronMan in 1978 that they changed the format because they didn't want bikes on the road at night. I certainly don't remember them changing the order around in the 80's. Can you refresh my memory? I do remember them changing the order around in the 90's in the tri grand prix but they never put the bike last. At least with the bike last, it doesn't matter whether you draft or not. The tactics would change so much.
I believe it's time to send triathlon back to it's original format. Swim, run, bike. Better yet, put the run first and we would also eliminate a dangerous swim start. I can understand having the swim first for novices but experienced athletes would manage fine and would train specifically for the transitions.
The ITU and Olympic elite races are draft legal, so you will see a big group coming off the bike together. In USAT non-draft legal races, wave starts have eliminated or at least minimized the problem. WTC needs to work on their Ironman races, but they sort themselves out on the hills in most cases.
This is something I've been thinking about lately. Swim does have to be first unless you want people to start needing rescues in much higher numbers. Then they'd outnumber the rescuers. And I don't think that biking would be too great after the run because a marathon is hard enough as it is-you wind up with people walking whether or not it's part of a triathlon.
I could see it happening on a sprint distance, but not olympic or longer.
The safety factor in the swim would be significantly diminished. Physically tired and/or exhausted triathletes entering the water, vice fresh, as is now the case. Logistically you would also have to have swim safety teams deployed in the water much longer as people would be entering the swim phase over a much longer timeframe, requiring the safety teams to be in the water for a significantly longer period of time. Better to get swimmers in and out of the water as quickly as possible.
Biking in the dark is obviously a bad idea.
The best way to break up a draft pack during the bike is to accelerate past it. At the end of the race, you know you followed the rules and the draft-packers can place an asterisk next to their finish time.
