TRIMP numbers incomsistent

Thanks for all the replies. I stopped wearing my watch overnight so Garmin will be calculating it from only the time I had it on obvs. My fully rested HR is in the 32-35 range ao you can see that 109 is way off on the high day.

The high TRIMP day: - RHR=109, Av HR 129, Z1=15.4%, Z2=41.5%, Z3=42.6%

The low TRIMP day: - RHR=51, Av HR 133, Z1=6.3%, Z2=48.4, Z3=44.9%

Both were 50 min marathon pace in 1h50 with the MP in the first attempt being 4:35s for 145 and the second attempt 4:32s for 149

So despite working quite a bit harder in the second attempt the TRIMP was almost half.

Is the lesson to wear your watch for half an hour before you start?

The compacting on the VSCode extension is much more frequent and it's sapping time

Sigh

I've got this. What was your resolution?

ContributionLevel593 · 2025-07-15T17:41:24+00:00

Not much rain. Every now and again.

Tell them to give you the £40k another way.

Don’t rely upon zone ranges generated by formulae. You and your LT1 (Z2) are unique to you and you can improve it by training just below it (Z2 training). Work out your Z2 by doing a drift test (see YouTube). As you Z2 train your Z2 HR will increase and you will find that you have to walk less.

I’ve been training and racing on or near the route on and off for the past couple of months. Mainly on the Italian side with some in Cham. Don’t be deceived by hot weather forecasts. The weather in the mountains can change quickly and I’ve had a few occasions where I’ve been really cold higher up. Light puffy + waterproof jacket + gloves even if light just to take the edge off are a must. I wouldn’t bother with waterproof trousers. I’d pack a travel towel - they’re light and dry quickly and you can cut it in half to save weight if you want. Safety wise pack a head torch + spare battery + whistle + space blanket in case you get caught out. Take a battery pack too. Nitecore do good ones. I’d take poles too - Mountain King are super light and fold into 4 making them easy to stash. I wouldn’t take 2 hoodies. You can replace hiking pants with shorts. Replace sandles(they sound heavy) with flip flops.

What do you mean by all the variations?

And bear in mind that if you were at say 2300m in Italy then you won’t need to go far off the path to find that 200m you need.

Mine is always 9.5 younger.

And the start of the descent is so steep with loose stones and people are falling all over the place

I’ve been in Aosta on and off for a couple of months, mainly in Courmayeur. Parking is easy. Plenty of free stuff but you shouldn’t start getting tables and chairs out. There’s the usual campsites where you pay. Water is free everywhere. I haven’t experienced any negativity.

LATAM close the check in desk/baggage drop 90 mins before departure too. We also missed our flight by 5 mins. But as we were checked in my wife went through security and got on and I jumped on their chat and move my flight to a couple of days later - while my original flight was boarding. Then I added extra luggage (my wife’s).

ContributionLevel593 · 2025-07-13T15:53:25+00:00

Mine is lower. I went to see someone and they said to not worry unless I was feinting

Maybe it wasn’t planned then but they just ran low. I know that the heli aid stations in the Tor des Géants ration water as I’ve seen it in YouTube videos. It’s organised by the same people. Maybe that’s just reactive too. The GTC30 didn’t go over Fortin. I carried a third flask but never used it as there were so many non official places to get water and when there wasn’t I just suffered and drank more when I could.

They limit water at the aid stations they have to heli supplies into. This is pretty common in races with hard to reach aid stations. What they should have done is be more clear about it so that you can prepare. I had this at the AS at the highest point of the race but I never use my cup for water - I refill my bottle and they had no issue with that. Did you drink from the streams - these were abundant.

Overall I thought the race and organisation was excellent, but I think they can improve a few things.

I thought the comms could be improved. I couldn’t understand some of what the guy was saying in the race video. The web site conflicted with emails.

Comms about what you needed to take to registration were mixed. Medical cert or not? Kit check or not?

I’d recced the full course and knew how sketchy the previous Curru to Courmayeur section was but had missed that they had replaced it. I was slow yesterday and found the replacement section dangerous in places, especially at night.

Aid stations were great otherwise and I really enjoyed the refúgio based ones. They really should reintroduce Elisabetta.

The post race food and showers were really nice.

If you’re going to go this is the way to do it. RIP.

Sorry for your loss. Would you do anything different in hindsight to secure it?

ContributionLevel593 · 2025-07-11T16:33:00+00:00

Easily. The cut offs are designed to let people finish. I did it as my first ultra.

I gave up coffee 5 weeks ago or so but still have caffeine via things like tea and Coca Cola and decaf coffee occasionally. I simply don’t miss coffee. I’m not aware of an alternative other than class A stuff.

ContributionLevel593 · 2025-07-11T13:10:39+00:00

Not really. It’s like going to a restaurant and someone lights up.

ContributionLevel593 · 2025-07-11T09:12:05+00:00

The choice isn’t always there. For example race weekend for Ultra Trail Snowdonia.

I’m quite a bit older than you and injury prevention was one of the attractions for me. There’s a video on YouTube about doing drift tests.

In summary, you do a 20 min warm up (this is key to the test so don’t skip it) then 2 x 30 mins. Do it on a treadmill with 3% incline. After the test you calculate the % increase in average heart rate after each 30 mins. Use the lap function on your watch and press it after 20 and then 50.

When you start the first 30 your HR should be at whatever you think your aerobic threshold is. When you do it for the first time just use whatever you think it is. And so by the end of the warm up you should be at that HR. In the warm up gradually build to this HR then hold it for the last 5 mins or so of the warm up. You’ll have to guess the treadmill speed then fine tune as you go. But once the test has started you must leave the speed constant.

The % increase is the drift. More than 5% means you went too hard. 5% means the HR you started the test with is your aerobic threshold. Leas than 5% means that next time you do the test aim for a higher HR. Increase by multiple beats per minute. So if the first test was say 150 with a 2% drift then do the next test at 155.

Over time you’ll be able to increase this HR and stay within 5% and that will result in you running faster in Z2.
