I think it's time we talked about lube...

Bodyglide has been plenty for me with everything. On the bike, if I need something more then I likely need to time the standing breaks a bit better and/or keep my hips more steady depending on what type of feeling develops. I've tried the Asos cream, but it was actually too slick. Never felt a need for more than bodyglide on the run. I've never bothered to reapply in the middle of a race and have had no trouble. But if history has shown you might need it, then would recommend taking the extra minute to do so as an already long day will become much more so. No need to make long course feel longer than it already is.

I wear dark colored shorts See my pic for my tri suit.

Wetsuit, I use body glide at then ankles, back of knees, armpits/shoulder area, and neck area.

Bike, vasoline applied copiously prior to the swim along with bag balm.

for HIMs I am fine the entire time. For my IM I have done, I stopped at special needs and reapplied. So it seems that the swim deteriorated some of the lube as I have done 4-5 hour rides with lubing up in the beginning and have been fine.

I am new to the tri game but I have a cycling background, so for the bike i use DZ nuts, i have had good success with it. Not too sure if it will stay on during the swim, im pretty sure it will.

Bag Balm

I use TriSlide for my wetsuit including the back of the neck.

Now, onto chamois cream:

Chamois Butt'r - good stuff for general use. It wears off/out at about 1 to
1.5 hours.
Chamois Butt'r Eurostyle - same time limitation but definite WOOHOO factor
when you're putting it on.:

Sportique Century Riding Cream -
This stuff ROCKS! It smells like fermenting beer, though. Works for up to 5
hours as far as I can tell
WONDERFUL stuff. has a beer/hops/yeasty
smell that I kinda like. The smell is easily identified two or three rooms away
so it's not exactly subtle. So far I've done 5 hour rides with it and not a
single problem plus it cleared up an irritation spot I had from the last time
my cream wore off. Less expensive than Assos.:

Beljum Budder -
This stuff works well, has been great for up to 6 hours that I've tried
it. A little thinner than the other two. This is what I use now for all rides:

Assos -
great stuff as well. It doesn't wear off and works even when you put
it on before the swim and forget to put more on for the bike.
Excellent stuff. A touch more expensive than the others but worth every
cent:

Bag Balm - gets into everything. Coats the seat. Works like a champ for up to
6 hours and is relatively dirt cheap.
petroleum jelly based. It's a little thick for me anyway and even
when I'm burning up it's still molasses.

DZNuts -
Not worth the effort for me. Wears off after about an hour or so.
Does well until that, though.

Asics Chafe Free Endurance -
really good and right up there with the Assos
but is a different consistancy. REALLY expensive but I'm going to keep a tube
around if I find it. There are a number out there now for runners but they're
in 1 and 1.5 Oz tubes for about $5-10 so they're not really affordable for
the long term.

Body Glide -
doesn't work for me as a chamois lube. Works great for wetsuit
removal but I think I sweat it off in about 10 seconds on the saddle.

A lot comes down to personal preference. Daniel gave a good list, and has obviously tried many different things. Body Glide doesn't work well for his undercarriage, but for me it works well. That's all I use for chafing, applying it liberally to the back of my neck before long wetsuit swims and to the areas I tend to chafe from the saddle. Are you sure the white you saw in your photos was Vaseline and not salt from sweating? In longer races for most people and all races for salty sweaters, salt marks are common on darker color clothing.

Based on Daniel's previous post on this issue (which is a hugely beneficial service - thanks Daniel) I started using bag balm to lube up the boys. Put on generously before the swim and the stuff is still there at the end of the run. (I use the stuff for bike workouts too, not just races) He is right tho, my saddle now permanently has the scent of bag balm. For potential chafing at arm/neck holes in my jersey, I use body glide.

A bit off topic: At my last race I just stood there in the middle of transition pre-race, grabbed a big handful of bag balm, shoved it down my shorts. No one looked (that I know of) or if they did, they did not care. Just proving what others echoed here: In transition the lube light is lit.
