| Marie Sklodowska Curie was a mother of 2 girls. She was born in Poland, but educated in Paris. Basically, she studied rocks in an old shed and discovered that radiation does not come from the interaction of molecules but instead is due to an intrinsic property of the elements' atoms. As long as I have been an adult, she has been a person I have looked up to and the a number of Swedes did see it fitting to give her a Nobel Prize in both Chemistry and Physics. |
Perhaps a good, albeit dark, segué to discuss ultrarunning.
Many (especially new) ultra runners may be surprised to know that running ultramarathons appears to affect the right side of the heart. Whether not it is strain (and dangerous) or an adaptation (and advantageous) is not known (Heidbuchel, Oxborough, George, etc); it may be an adaptation that in the short term is good, but in the long term causes arrhythmias. In running longs distances, we experiment as we go. Humans have always run, but races this long?
Post ultra fever
3 days after the Fyr til Fyr 60k, I developed my usual post-ultra fever. I felt terrible and had to force Mattias to go to bed early with me. It seems most reasonable to me that this is a result of a cytokine storm (in response to high levels of adrenaline +/- muscle breakdown) rather than an infection (see Pedersen, 1997), but studies of blood work multiple days after an ultra are difficult and expensive so they are few.
The most recent fever was nothing compared to the fever I had 3 days after 3 days of Syllamo where I was so delirious that I had to call 911. It got so high that I could not watch a newborn and SR ironically was on call at a different ER and couldn't leave. There have only been a few moments in my life where I wondered if I would survive and they have all been following ultramarathons (I don't drive much).
Then there is my diet experimentation: low carb, high fat
Our kitchen is at all times filled with pots, pans, cutting boards, loads of veggies, nuts, cheese, eggs, fish and tofu.I have never been one to get into cooking, but anything in the name of science! Burners and blenders constantly going, it is kind of fun, though time consuming. (by the way, it is nearly impossible to be a pesco-vegetarian and eat a truly high fat diet, but again, I think it is the low carb, no added sugar that is the most important part).
My newest discovery is ground flax seed in unsweetened soy milk.

Again the reason for all of this is to 1. eat naturally, 2. keep my blood sugar more constant and 3. teach my body to rely more on fat as a fuel source.
My experince at Fyr til Fyr was evidence for me that my body is better at using fat for energy than before (evidence was needing to eat way less during the race). Additional evidence is Zach Bitter's continued ultraruning success (did you guys see him break the course record at the Mad City 100k? (I'm not saying it is not ALSO his training) - he is also on an all-natural, low, carb, high fat diet.
BUT- after I ate the above for breakfast AND lunch (very high fat and high protein), I got up quickly after Bikram Yoga and actually fainted in the locker room. As I stood there, feeling sick, knowing I was about to topple over, I had the wherewithal to think: "this is what happens when you experiment too much!" (it was probably because I got dehydrated from digesting a super high fat, high protein series of meals).
Have I mentioned that I have lost over 4 kilos since starting this diet? As I stood there giving my "Runner's Diet" talk to Sparta, I talked about how I loved the fact that I never weighed myself and, on this new diet, just went by feel. Well, after two months, I figured I had better step on the scale--49 kilos!?
(either this is the weight my body wants to be - I still feel great, actually better than ever - or I need to blend and boil a bit more in the kitchen)
Training by Menstrual Cycle
This is not much of an experiment, but I love getting regular periods (this is the first time in my life I have) and the sure sign that one is coming is I write to coach Ole "I don't feel like running" - and then 1 to 2 days later, there it is. Estrogen levels drop dramatically (the female equivalent of testosterone) right before menstruation so it makes sense training (or racing) is not optimal at this stage of the cycle. A study I read recently in Medicine and Science in Sports and Exercise found that women who are on birth control pills don't have the same physiological changes during their menstrual cycles, but those not on hormonal contraceptives actually get significantly stiffer when their estrogen level is lower. (Casey, 2013) I am sure other "things" happen, but stiffness was the endpoint of that study.

Vitargo
My next experiment will be with something quite different before and during my runs: Vitargo. It is a Swedish-made carbohydrate source for athletes that is made with maize, maltodextrin and sugar. No, this is not part of a low carb diet, but will give you quick energy while training. Pia Joan, Jesper Noer and I have been asked to test it while ultra training. Jesper had a great experience using Vitargo at Fyr til Fyr. Thanks to Mikkel Halkjær of Sport4Fun for delivering this to Fysium today:
Yeah, so I plan on using the blood sugar monitor regularly to see what is really happening with my blood sugar. One thing is "feeling" a certain a blood sugar, another is getting a reading. I will keep a Stata spreadsheet; don't worry.
By the way, that green couch was hand-made for me when I was 18 years old. It has travelled a lot.
So, the glucose measuring is just to point out- you don't need a lab to experiment: you can get away with a Marie Curie shed or a tiny apartment in Næstved.
Another thing I look forward to experimenting with (Thomas said I could :-)) and following other peoples' experiences with is the Alter-G treadmill at Fysium. There are only 10 in Denmark.
Now some pictures from a great pre-Easter week

| Today's workout was simply 200 + 6 x 800 meters at "moderate" pace. I could feel I wanted to go faster and that my legs are doing well again after Fyr til Fyr. |
