[Event] Tshwane Classic

[Vetplant]

Jirre, you one water bottle maargatte. [emoji39] On a hot day ( say circa 30C or more) a bloke like me goes through 3 to 4 bottles quite easily on a ride like that!

Ja, on a bleed-through-your-eyeballs race like 947 in November, 2x full bottles is actually cutting it very fine... Last year I did an F1 style splash and dash at the entrance to Kyalami, my bottlecap was already open and the guys were pouring before I had even come to a complete stop.I was already dropped from the main bunch, so was worth it to stop and top-up.

I am sure they will cap it on entries. Thats what they did at fat Sheep. First 500 that entered and paid got into the race. They then arrange batches accordingly depending on the number of entries per category.

 

That not ideal, but 30+, 50+ and elite ladies had 1 batch.

 

Elite men own batch. 40+ also own batch.

For licensed categories, the CSA officials will determine the number of batches. They usually group 50+ and ladies, 30-49 and Elite, U23 and Juniors together. They then have officials to watch each age group, so three in the 30+, 50+ and ladies.

The trouble with a cap of 500 on a race and 50 per batch, there's no knowing how many per category will take part. So instead of usual batching, at Fat Sheep they obviously tried to make up a batch of 50, and the mix depended on the number of entered riders in a category. Hence 50+ and 30+ in 1 batch with a few elite ladies.

Cycle4Cansa had :

-566 finishers at the 104km distance

-242 finishers of the 70km

-3 finishers of the 10km (yes, three....)

 

So the total cap of 500 seems to be "just a guideline" to some organisers...

Have you seen the route of the 10km ?

Not sure if its changed, but many years back when my wife was not yet my wife, we got her and my mates girl at the time to do the 10km whilst we went out and did the 70.

We didnt bother checking the route, only to find out after the race that is started somehwere in the parking lot and then climbed that hill into Sun City, now as 2 unfit young ladies doing their first race you can imagine the swearing we were subjected to.

This maargat used to go through 6l of water on a 130km race.

Now I do 1l

 

You teach yourself.

And over hydration is a thing I have learned...........

What I struggle to understand is why I can run about 2 hours without the same amount of consumption that I do on the bike.

 

My stomach is very more accommodating during a cycle because it isn't shaking about violently. So maybe it is just that I am consuming these quantities because I physically am able to , I might NOT need it.

 

Seeing as running is arguably of a higher intensity, so cycling on less should be more than achievable. Just need to teach the mind...?

[Nico van Loggerenberg]

It really depends on the weather as well.

Fat Sheep, I don't know how many people entered but if you look at the results only about 300 or so actually started.

Spinnekop, it's true that as I've become fitter and stronger I have also found that I need less water than before. I don't fully understand why but it is true. But... If you speak to a nephrologist (kidney specialist) they'll tell how incredibly hard these endurance events are on the kidneys and how you can permanently damage your kidneys (friend of mine did on last year's Amashova). You simply have to drink enough fluid.

 

My coach (well known former pro) says that on a hottish day, one should be drinking about a bottle an hour.

 

We're all different, genetically and otherwise. Maar wees net 'n bietjie versigtig met jou niere. Kidney replacements can't be had at CycleLab....

 

Use it, don't use.

Vetplant, not sure but suspect air movement on a bicycle leads to a (much?) higher fluid loss rate. I used to find the same when riding motorbikes long distances in hot weather with light clothing. You lose a lot of fluid. Even though you're just sitting there.

Very good theory 

 

Perspiration rates is probably a science in itself.

[Long Wheel Base]

Extra bottles means extra weight, no thanks.

Prof Ross Tucker is very smart.

 

We’ll tell you how good intentions plus marketing paved a road to lethal dangers for athletes, how humans are meant to dehydrate, and why thirst works just fine for your hydration needs.

For this post, we acknowledge Professor Tim Noakes of UCT,

First paragraph ^^^^

 

Already has the spidey sense tingling.

But I'll continue reading, there may be some good points to consider.

Ross Tucker was a grad student under Tim Noakes at one point, and although they had a falling out over the whole carb vs low carb thing and don't speak to one another anymore, and I agree with Tucker that Noakes' carb rant is garbage, Noakes did a lot of good work across sport.

 

Also, if you read all 4 parts of the hydration post on Science of Sport, they don't reference any of Noakes' works.

 

What I mean is just because Noakes shat the bed on the whole carb issue, doesn't mean you have to throw out the baby with the bath water.

I'm about to start on part 3

Part 1 read very much like a conspiracy theory, but part 2 shed some good light on the matter.
