In my opinion, you're doing good with taking 5 minutes between the two disciplines. My collegiate tri coach always said it is best to do it within 10 minutes which I always thought to be good. If you consider transition times your 5 minutes for non race transition is not too bad. And maybe you are getting alot better, after all, the point of practicing brick workouts is so your legs get used to that feeling after the bike.

As long as you are moving along and not just farting around while getting changed, you're doing fine. During the summer, I often change shorts during my transitions, so no, I dont have my race T times in the 60 second range.

I agree that you want to closely mimic race conditions but within 10 minutes will get you the results you want.

If I'm doing a true brick (as opposed to just back to back workouts), then I tend to be under a few minutes. Basically just enough time for me to park my bike in the garage, take off my shoes/helmet/gloves/bike shirt and switch to running shoes/whatever shirt. Maybe 2-3 minutes tops.

I guess the benefit I get out of bricks tends to be the first 5-10 minutes. After that point my running has pretty much stablized and I'm on autopilot. My biggest issue is actually going out too fast into the run segment (in a race) because my body feels slower than it's really going after travelling at high speeds on the bike. Kinda fun..but also scary as crap when you realize your running splits you simply can't maintain for the given distance.

For mid to long training runs, most advisors suggest that you integrate walking intervals (e.g. for every 15min of running you walk 2min). The purpose of this is to periodically provide fresh legs so that your run periods are more effective. It seems to me that if you're grinding along on the run after a 1-2 minute T, you're probably not getting the most out of your early run stage(s). However, if you feel great after a 5 minute T, then you will probably start out running with better form, greater efficiency, and less fatigue (thus, making up for the extra 3 minutes). As mentioned above, this is especially true for longer runs, where giving up 3 minutes is like spitting in the ocean.

Per UFTriGator's return comment (above), I'd like to add that the advice on walking, and my opinion on getting R&R in transition, are related to overall conditioning and base training. By definition, bricks are race simulation, so if you don't plan on planting your rear for 5 minutes in T2, your eventual brick training should reflect that. In hindsight, my comments are more applicable to back-to-backs rather than bricks. Point taken.
