Second/Last Race Rehearsal...VERY different from first

Team, would like some feedback on my second RR that was yesterday.  A little bit of background...

- A race is Florida 70.3 in two weeks.  Been having good training, not perfect, but life has thrown some curve balls.  Almost all big days have been completed.

- Race is expected to be very hot and humid.  Of course, a cool front came through and it was very cool and pleasant.  So...

- RR was done on a 7 mile loop.  Hit the lap button every 14 miles, so I split it up mentally into quarters.  That's also when I hit the lap button.

Lap / Lap Time / Distance / Ave speed / AHR / Ave cadence

41:23 / 13.70 / 19.9 / 124 / 89.6

39:11 / 13.69 / 21.0 / 128 / 84.6

39:23 / 13.72 / 20.9 / 130 / 85.3

39:09 / 13.68 / 21.0 / 134 / 88.2

02:02 / 0.60 / 17.6 /  137 /  74.8 (*from end of loop to car)

Total time = 2h41m11s, AHR = 129 (Z2 starts ;roughly 133), ave cadence = 86.8

Pee stops were at 38', 1h20', and ~2h.  I drank about 2 aero bottles of water, and ~2.5 bottles of powerade Perform (what's on the course).  drank every 5'...alternating between water and powerade.  I had a salt tab at the 1h and 2h marks.  Don't recall when I refilled.  Total breaks were ~8 minutes.  So, actual time on the road was 2h 49 minutes or so.  Original goal was to drink at least three bottles of water and powerade, as that's what I think I'll need because of the heat.

I was overhydrating, so I dailed that down a bit the second half.  I was having to go tothe bathroom too much.  This has to be a function of the cool weather.  But it was strange because I was VERY thirsty at the end of the ride, and my mouth was dry at the end of the run.  Speaking of which...

M1- 8:47.9, AHR 141

M2 - 8:53.44    145

M3 - 8:33.80    153

M4 - 7:55.78    164

M5 - 7:58.92    168

M6 - 7:55.74    171

This isn't bad at all, but I was shooting for 7.40 miles for the final three.  I knew my HR was beginning to climb, and I was dehydrated.  I had a waterbottle of EFS Liquid Shot diluted in water, and a water bottle.  Had a sip of that and plain water every mile.  No cheating on that either.

I don't know if I could have held that pace or not for 6 more miles, due to HR peaking at Z4 (Z4 srtarts ;roughly 173 or so).  I go more by pace than HR, but I just kind of know when I'm reaching that point.

So, what did I discover?  I planned this better than last time (my run was terrible last time). But the weather being cooler did me no favors.

Is there anything I missed?  I think I'm looking at a 2.40 bike and ~1.40 run...maybe a bit faster, as I'm planning to have a disk wheel and HED3 race day.

  • I'm wondering if I should have pushed harder on the bike. If I need to be mid-Z2 average, I was way under. But it sure as heck didn't feel like I was under-pacing. Especially into the wind. Maybe @ 22mph, that would have been a bit more ideal?
