Along with winter’s weather comes also the shortening of days, which poses some difficulties for us runners, who hate to run indoors. Winter weather means bad road and trail conditions that in conjunction with still present leaves from fall and dark conditions pose non-negligible risks for ankle sprains.

Being a triathlete (or runner) means having a lot of running shoes. And that count goes up to gazillion pairs when living with a runner, which poses quite big storage problem.

The need for energy intake during prolonged activities is greatly reduced while being on Low Carb nutrition due to greater reliance on fat for fuel. And we carry plenty of fat to get us nearly anywhere. But there are still situations, where easily transportable, energy and nutritionally dense snack may come in handy.



B017 race week mealsRace week meals – IM France

I already described my nutrition tapering on my blog previously, but have received quite a lot of questions regarding actual meals. I can understand that it can be quite difficult to measure the chosen amount of carbohydrates without proper food tracking (i.e. food weighting), so I decided to take pictures of all my meals in the entire race week.

In 2013 I decided to do Ironman France for the same reason I did Ironman Lanzarote: because of challenging bike course. Besides preventing excessive drafting on race day, applying for races with hard bike course “forces” you to train harder on the bike.

This is one of the most frequent questions I received since switching to Low Carb High Fat nutrition. It almost every time goes something in the line with “…your cholesterol must be off charts because of the high fat intake…” As it turns out, 2 common myths about heart disease are wrong.

It was on 23rd November 2012 when I first heard of Low Carb High Fat (LCHF) diet, when Klemen sent me one of the articles by prof. Tim Noakes and wrote bellow “This needs to be tested!”.

Podcast are a great way to shorten your time while holding a plank position. Or any other strength exercise, especially those uncomfortable positions that make your muscles screaming in search of “time forward button”.


Your Best TriathlonTriathlon training books

Many of us amateur athletes are self-coached, for various reasons. It may be due to lower ambitions, because of financial constraints, lack of good coaches or something similar. I, for instance, enjoy coaching myself because I like experimenting with new training principles and blending them with established facts, observing effects and analyzing results.


B01101 Volume comparison Training Low

Carbohydrates are undisputedly ergogenic aids for endurance exercise training. There basically isn’t a single study out there that shows a negative effect of carbs on performance. So when going Low carb in training period, your training performance will suffer, either in volume, intensity or RPE (rating of perceived exertion). I finally managed to perform an analysis of my key training periods before Hawaii Ironman triathlon 2012 (High Carb) and before Hawaii 2013 (Low Carb), that confirmed my initial observations and findings from scientific literature.

B00705 Period viewHow I track my training

On 5th February 2000 I ran 3,7 km in the time of 15:45. This was my first entry into training log, which was in paper back then. 3.757 workouts later (until 2014) I get very nostalgic when holding those couple of papers that were my training log at that time. Now in the electronic age, I cannot hold my training log anymore as it is stored in a cloud. Being data geek, this is how I track my workouts.

Skinfold measuring sitesTracking body composition changes

Human body is composed of several materials, some of which are muscle, fat, bone, blood, urine… So measuring or tracking changes in body composition with weight scale is pretty much like observing total points scored in basketball games – 153 baskets scored doesn’t tell you who won and by how much! And when you factor also gut contents, gut microbioma (over 1kg in adults!), glycogen content (with all bound water), urine volume, hydration status… into body weight, the picture becomes quite messy.
