Race - Semi-Alcoholic Traverse

Dscn5451Three weeks ago, Stano and I set out to do the Semi-Alcoholic Traverse. This is a high alpine ridge run from Brandywine Mountain to Cypress Mountain. Aparently the proper Alcoholic Traverse finishes at Brew rather than Cypress Mountain but we decided Cypress was a better finish on a more logical route and with a better scramble at the end. We made it up Brandywine in good time but turned around as the weather deteriorated.

Nick and I set out again to do it this week on a perfect crisp day. The hardest part of the traverse is arranging the cars, as you start and finish in two different places - both very far up logging roads. Having heard of epics involving mountain bikes and hitchhiking, we opted to each drive a car and do the shuttle.

Expedition - Nepal Update 2

Our second week in Nepal started on July 25th with a 6 hour drive to a small one hut village called Ramche. After Ramche, the road has been broken into small sections by several landslides so from here we had to hike the majority of the way.

Lining up to cross the landslide.

Nutrition - Fuel Comparison

Without proper fuel, a ski tour can turn into a day of unnecessary suffering. My previous post covered some basic concepts for fueling. This post compares some of the different options for fast energy on the skin track.

Gels

GU comes in with the most calories but also at the second highest cost. All the gels use maltodextrin (a complex carbohydrate) as their primary ingredient. GU and Hammer contain a variety of amino acids. All four contain electolytes in varying amounts and each uses some type of preservative (Potassium Sorbate in GU, Hammer, CarbBoom. Potassium Citrate in Cliff). Cliff Gel is also advertised as certified organic.

Pre-event fuel is just as important. I will cover this in another post. (Sarah fueling up for a big day of skiing.)

As far as taste goes, I am happy with GU, Hammer and CarbBoom. Cliff leaves a little something to be desired but still no complaints. I am a big fan of the leash on the Cliff Gels that prevent you from losing the top after you have ripped it off - I wish GU would incorporate this feature into their gels.

Solid Energy Blocks:

GU Chomps:

  • Size: 60 grams
  • Cost: $2.90
  • Calories: 180
  • Total Carbs: 46g
  • Sugar: 22g
  • Electrolytes (Sodium & Potassium): 180mg
  • Caloric Density: 3.0 kcal/g
  • Cost per kcal: $0.02

Cliff Bloks:

  • Size: 60 grams
  • Cost: $2.10
  • Calories: 200
  • Total Carbs: 48g
  • Sugar: 24g
  • Electrolytes (Sodium & Potassium): 180mg
  • Caloric Density: 3.33 kcal/g
  • Cost per kcal: $0.01

Honey Stinger:

  • Size: 50 grams
  • Cost: $2.10
  • Calories: 160
  • Total Carbs: 39g
  • Sugar: 27g
  • Electrolytes (Sodium & Potassium): 120mg
  • Caloric Density: 3.2 kcal/g
  • Cost per kcal: $0.01

Sharkies:

  • Size: 45 grams
  • Cost: $1.75
  • Calories: 140
  • Total Carbs: 36g
  • Sugar: 17g
  • Electrolytes (Sodium & Potassium): 140mg
  • Caloric Density: 3.13 kcal/g
  • Cost per kcal: $0.01

Here, things are a bit more equal. Cost is pretty much the same all around. Caloric density ranges but GU and Cliff contain the most calories per package which gives them a bit of an edge. Again, the ingredients are fairly similar. I think the Sharkies taste the most like candy. They also are the most chewy, something that I don't like when working hard. The GU Chomps are my favorite flavors and a good consistency. I would like to see leashes on these as well.

It's hard for gel to compete with summit Dunkaroos (Mt. Baker).

Final verdict: GU for the win in both categories but I think all the options are good fuel choices.

Nutrition - Skimo Fueling

Nutrition strategies during a Speed Traverse or Skimo Race.

Dscn2902I wanted to detemine the optimal fueling strategy for an upcoming attempt at a fast - in a day - speed ski traverse. This is an approximately 4-6 hour effort with significant time spent climbing. Saturday's attempt at the Garibaldi Neve is a good example of pace for a trip like this. My average HR was 145bpm overall but closer to the 160-165 range when skinning. A 4-hour effort that cost me around 2500 kCal according to my Suunto t6d. That translates to burning around 625kcal per hour. With longer or harder ascent sections, it could easily be in the 650-675 kcal/Hr mark.
