Nah not doing much reading. First and last marathon in 30 years. I will get round thats alk I am interested in. Few extra bob for muscular dystrophy research then back to real life. Our lass has got a serious health issue at the mo and buggering off running for hours at a time wouldn't br fair.

Yup. Me too. Hoping just to get around. I'll be happy with 5hrs. I haven't cracked an hour for 10k yet...

I've run Livonia parkrun in Detroit 3 times, and I'm buddies with they guy that runs parkrun USA. It's a small world eh?
 
im feeling confident to get under 5 now, i did the 20 in 3:22 but reckon i could have done it quicker, i did a really nice 10k in richmond in 55 mins, but getting round is plan A
 
there was a fella in my local parkrun that travels the country each week doing different one, he had done loads 200 odd if i remember, he gets there all on public transport too

last week they started one in reigate, surrey which is on my way to work so im switching

once i win the lottery i may spend my life travelling the world doing parkruns :)
 
I did just under 50 mins for the Leeds Abbey Dash 10k. Knackered my legs since then though.

http://www.parkrun-barcode.org.uk/ do the official plastic cards and tags. Good value in my opinion.

I have done a few different parkruns now. Huddersfield is my home one. Also done, Clumber, Temple Newsam, Dewsbury and Fountains Abbey. Very attached to Huddersfield but now the numbers are around 600 it can get a tad busy.
 
Just to say the £6.75 inc. posting is actually three (small) plastic tags and a credit card sized tag.

They get them made and posted quick as well. very professional.
 
I think there may be a million registered worldwide but not everyone does a parkrun every week.

Still impressive figures and free.

My intention is to run the Berlin Marathon on zero carbs. It's a bit of a risk, and I need to see how it works out in training, but see an increasing number of zero or very-low-carb endurance runners as suggested by Volek and Phinney in 'The Art and Science of Low Carb Performance".

I think the trick is to make sure that you are in deep ketosis through the last couple of months. I eat very little carbohydrate (<25g) but I do a pretty bad job of getting high blood ketone levels unless I'm running a lot, probably because of insulin resistance. Hopefully the late stages of the marathon training plan will tip me into "deep purple" territory.

I've invested in a couple of bottles of this: http://prototypenutrition.com/ketoforce.html which I intend to use on the day. Technically it's "juicing", but I figure that it's no different than the carb heads fueling up on pasta. The rumors are that this stuff is what helped Chris Froome win the TdF. I might dabble with some SuperStarch too.

Wow! That is pretty extreme.
I am interested to take a look at who/where you've referenced. If memory serves me correct your liver should have approx 100g of 'glycogen' stores, and the muscles have approx 400g, which according to some can take you as far as mile 18 of a marathon without taking on any additional carb. I can appreciate however that if your body's energy pathway is already set to burn fat over carbs, this could be different.
Very interesting - you are probably already familiar with how different energy sources are used according to how much energy you are putting in, but if you aren't the Type 1 case study movie on the Team blood glucose website has a table approx 2.55min in which you might find interesting. (Basically running slower will mean you can run for longer)
In reference to your low carb diet (an <25g is very low) I'm surprised you're not getting higher blood ketone levels. Remember you may be taking on board 'hidden' carbs - milk in a cup of tea will add 5g carbs, so a few cups a day and it ups the daily amount (not that I would want to encourage you further down that path!)
Carbing whilst you run is most definitely a safer option, though taking gels during the run will be like rocket fuel to your body - drink plenty of water to avoid getting an upset stomach.
Keep up the good work, and keep safe.

Thankyou i have had a look at this, the first review i read is here :)

Well, having participated in multiple Ironman triathlon, 70.3 events, marathons and 1/2marathons, I thought I would try this new "Wunder Carb".
First off, it tastes like someone put sand in your water. Then comes the taste. I got past that. Then about halfway through my work out I was exhausted, and had a gut ache. EVERY TIME I tried it. And I tried it at least a half dozen times. So today, I went back to my GU products. I had no gut issues, had a great "even keel" energy level for over 2 hours, AND I didn't get diarrhea halfway through my workout!

hehe, ill give it a miss, but sounded interesting for a second :)

Sounds like you're super fit Andy, I would be really interested to know what your training program/techniques are to manage your BGs and what med adjustments (if any) you make whilst you train, and if this alters at all during an event.

It is extreme. It may even be a little stupid. We'll see.
  1. Hitting the wall in a marathon is caused by hypoglycemia, when your muscles suck up all your blood glucose and your brain doesn't have enough to function properly.
  2. Through sustained ketosis, you can down regulate your brain's requirement for glucose from about 120g a day, to about 25g, meaning that your brain is a lot less likely to suffer from hypoglycemia (because you can make 25g a day from proetin and fat via gluconeogenesis)
  3. A side effect of this is that your muscles (trying to protect your brain) go into "glucose sparing mode" and begin to burn more fat, or at least allow you to run principally on fat at higher intensities than would otherwise be possible.
  4. But like you say, it's still a question of running slow enough, if you run too fast you'll end up burning more glucose and end up in trouble.

This is a good quick intro:

Thanks for that - looks like I have some reading to do!
I heard somewhere that if your body does go into 'starvation' mode, you can end up burning muscle (protein) when you exercise - do you have any thoughts/experience of that?

Hi Bebo,
I should say just over a year ago, i couldn't run a bath, so I'm making it up as i go along, i only take metformin and bp meds
My training isn't following a training plan, i tried to understand them but they are too complicated for me, tempo this and fartlek that, so i run three night a week, normally tuesdays 5k weds 5 miles thursdays 5k, park run saturdays and long runs sundays, I've just done my first 20 miler and the marathon is in a couple of weeks (crapping myself tbh) so I'm tapering, funny how i started following the marathons training plan at the tapering stage :) this sunday 10 miles next week 8 etc, I've followed my usual low carb 30g per day throughout although the last couple of longer runs i have taken in some carbs (yum) a bacon roll in white roll and an energy bar last week for example.

i am very worried about what i am going to do after the marathon as i seem to be cursed with needing the motivation of people telling me i can't do it, to do it, first the low carbing strictness of dealing with the diabetes, now the marathon, scares me to think whats next, i have a fear of heights so I'm terrified the next thing will be something high lol, if I'm not being told I'm being stupid I'm not happy :)

this is me at the 20 mile mark, i looked a whole lot happier in the photo than i felt because i knew the photographer was there, I've got other photos, when i didn't know they were being taken where i look my normal constipated self lol
