Poles for Ski Mountaineering Racing

I don’t come from a ski racing background (cross country or downhill). I didn’t know that you could spend $100 on a small brick of wax that makes ski bases so slippery that skins can’t stick to them. And I certainly didn’t know that you could spend $500 on a pair of poles! Frankly, I didn’t see the point of spending more than $40 on a pair of sticks that get bashed and crashed or lost, stolen, and forgotten. Fancy grips, pole straps, baskets, adjustment systems, and exotic materials promising greater strength, stiffness, and lighter weight don’t really justify the additional cost. I just wish that cheaper poles came with powder baskets, especially since everyone and their dog is now skiing on fat skis and should theoretically be chasing after scarce powder, not bashing gates on groomed runs.

Lately, I’ve been using cheap but flexy $20 Komperdell xc poles for my backcountry skiing. I don’t have much desire to change the length of my pole throughout the day. The skinny xc grips are pretty good for plunging into the snow, and the xc basket and tip provide enough float and don’t get in the way when I’m scratching across an icy sidehill.

But skimo racing is different. The clock is ticking. Each time I lift the ski poles up to plant them again further up the mountain costs me energy. I’m not a double-poling xc skier reaching high and crunching down low demanding ultimate stiffness, but I prefer not to have to think about my poles bowing under my measly single pole plants. So I use my trusty Dynafit SR Race poles. But like any concerning ski mountaineering racer, I’m wondering if they present the best bang for the buck, and what sort of performance advantages I can obtain for minimal costs.
This scale shot had me curious. Here Yannick Ecoeur's Swix Triax 1.0 ($400+) poles are shown to weigh 146g in what I am assuming is a 140cm length. XC poles are often quoted in g/m without grips and baskets, so it is nice to see a real world weight.
Ski mountaineering poles are nothing more than xc poles with larger baskets and straps that are easy to get in and out of (Leki’s shark system is also very popular for ski-mo), possibly with reinforcement. One can buy ski-mo poles off the shelf…er web from Dynafit, Ski Trab, La Sportiva, ATK-Race, Crazy Idea, Gabel, Komperdell, and Leki among others, but I wondered how the value of these compared to much more common xc poles, especially if they were placed on sale!

So I looked into the weights and costs of various ski-mo and xc poles. Many of these weights are claimed, some are verified by others, and some are estimated by comparing a verified or claimed weight of one pole to the unit tube weight (g/cm) of a pole from the same manufacturer. The measured and claimed weights (from skimo.co) were for lengths varying from 125-140cm, so to make for a fairer comparison of weight, I scaled them (g/cm, including grip/basket, although actual g/cm goes down as poles get longer). So after checking Skintrack.com for your optimum pole length, the DyNA will probably be the lightest out of the poles on this list. Lighter than many $300+ xc poles! Those black diamond traverse adjustable poles will be more than twice as heavy. Generic alpine poles (Komperdell Carv Pro) are also  near the top of the list of the worst g/cm.

XC and ski-mo poles ranked in terms of g/cm (less is better), either based on measured or claimed  weights(at 125,130,135,140cm) or estimated  from the claimed g/cm of the pole and adding the basket and grip (usually 60-65g). Interesting how there is a slight jump between the  Komperdell nordic classic and the aluminum Dynafit SR Race in the middle of what is otherwise a smooth distribution.

But what poles give you the best bang for the buck? I then compared the online sale price (retail is for suckers) multiplied by the g/cm. 

XC and ski-mo poles ranked in terms of $*g/cm (lower is better). Many aluminum poles have good $*g/cm as Aluminum is light and cheap! This high end XC poles have high $*g/cm.
Here my $20 Komperdells lead the pack. The Dynafit PDG pole seems to offer competitive value and light weight. My SR Race poles give up ~90grams to Dynafit’s best offering. And if you are interested in buying new poles, note that skimo poles like the Movement X-race carbon, Komperdell Nepal 10, Dynafit PDG Expert, and Gabel Piera Menta carbon give you pretty good bang for the buck, along with being pretty light!

What is the relationship between pole price and unit weight? One would expect that as you spend more and more, you are saving less and less weight. This is an exponential relationship and it is plotted below.
But how does ski pole weight affect exertion and overall race times? What about breakage? I've only seen/heard of carbon poles breaking (PDG, RSR, DyNA, "CT1 are too fragile for skimo").

*Updated 2016 with Black Diamond's poles. Vapor 1 and Helio are extremely competitive weight-wise. Will also add Dynafit Speed Vario and C2 ultralight, 2 adjustable poles that weigh ~180grams! Dynafit PDG pole is now the Dynafit Speed pole

Castle Mountain Skimo

The race season kicked off January 11 with the 3rd edition of the Castle Mountain Skimo Race. I enjoyed the relaxed Sunday start as it meant that I didn't have to take time off work to show up to the race with reasonably fresh/rested legs.
Some poor one-handed pole action through the technical terrian


I helped out with a clinic on the Saturday before the race where we showed attendees the wonders of of kick turns and transitions.

The hill was pretty hurting for snow so the first climb was a heinous battle through the alders. There were also a couple of short descents to dance around fallen logs and alders. I think everyone was pleased once the skintrack rose into more open terrain.

The low snow year also meant that the bootpack, that started with a downhill section was extra spicy with more exposed rocks. The lone star descent was predictable wind pressed snow with an exposed traverse above the bare "midriff" of the run adding some technical nature. Don't fall (or you might break a femur". The 2nd and final climb was familiar from last year's modified course with steep climbs to make sure that you had something left in the tank. The final descent down the cat skiing area would have skied nicely, but our short and skinny race skis could not float very well in the baseless snow.

German Philipp Schรคdler showed up and sped off from the start with a pace that only Travis Brown could match. Through the alders I found myself in no-man's land just ahead of Oliver Bibby and Steve Sellers but losing ground on Travis. Young Olie caught me on the bootpack  and passed on the descent before crashing. With Steve joining us at the transition for the final climb, I had my work cut out for me, put my head down and set a pace that nobody could match. 3rd place, but a whopping 20 minutes behind Philipp and 10 behind Travis!

Vert 180 and a couple of hut trips

A bit of a slow start to the season for me, but I Travis and I got 'er going with an overnighter over a long weekend.




Jumbo Wild


Great snow with a packrat and some sledders to keep us company.

Vert 180
Even with the lack of skiing, I felt pretty good at the Vert180 and finished 2nd behind Travis. No hip flexor pain, so things are looking good for this season!


Asulkan Camp
With tired legs from racing hard for 3hrs and tired bodies from frantic late night packing, meeting at 9am at the Asulkan parking lot was out of question. We ended up leaving Canmore at 9. The ACC had taken a page out of Alison Redford's playbook and generously block-booked the hut for us so we would have lots of elbow room to eat and sleep as just Michelle, Martha, Steve, Travis and I were attending. 

After a 3hour ski up to the hut, through tracked out snow and watching numerous groups ski down, the sleeping bags and hut booties seemed more inviting than a couple of short laps above the hut in wind affected snow. 

Monday brought a lazy start but with some ambitious goals. None of the weekend groups had skied above the hut and the weather and avalanche conditions were looking good, so we set our sights up to the top of Youngs Peak. Travis punched the track up the steep headwall and we quickly topped out. I was expecting to pound out a couple of laps on the steps of paradise, but soon we were skiing down the other side towards the forever young couloir. which was untouched since the last snowfall. Meanwhile, some German ski mountaineering racers had topped out the couloir from the road so I had some company at the top while I waited my turn. We all made it down safely with varying levels of slough management techniques depending on what order we dropped in.

Typically these camps are a chance to ski lots of vertical, but with tired legs from racing this adventure was an interesting diversion. After a couple of afternoon laps of the triangle moraine, the legs were getting tired, the light was fading and it was time for a classic staple of these SMCC Asulkan ski camps: The bonk-slog up the tree triangle back to the hut at the end of the day.

Shortly after the last stragglers arrived back at the hut, the wind got much stronger and battered the hut all night. The wind sustained through the morning and brought warm temperatures along with it. Freezing levels rose above the hut, motivation levels did the opposite. Trees were uncovered by the wind and their snow was blown into the outhouse thanks to some broken locks. And it was raining. It was time to bail.

The ski down from the hut was interesting as the snow got slower and less supportive as we worked our way down the tree triangle. The snow could be described as elephant snot or fluffy powder depending on whether the person you were talking to was from Fernie. On the way down we encountered what is likely another full house at the Asulkan. Nobody was pumped to hear that it was raining at the hut.

Well at least I got back to Edmonton at a decent hour!

Wapta in a Day

6:35!
Beauty day on the Wapta. Full report here

Joffre in a Day

Saturday, April 24, Travis and I day tripped Mt. Joffre. It was my second attempt at pulling that off after bailing high on the face with concerns about stability due to wind affect.

The long weekend started off with a snowy good Friday where we skied powder and got chased by wet slides.


With the recent snow, I wasn't too keen on the Wapta traverse, but Travis was ready for something big, so he suggested trying Mt. Joffre.

dry up high, wet down low

Tire change crossfit

Early morning skate across Upper Kananaskis lake

Nearing Aster Lake after ~2.5hrs

Approaching the face after having passed 2 parties who were camped at the lake


Summit! my first 11,000er



The lake is still (kinda) frozen! Just under 11hrs car to car



Not as great weather on Hector

Dogtooth Dash and Vert 180

I apologize to my regular readers for the delay, I just have not been very motivated to write when there is TV to be watched, Facebook feeds to be scrolled through, and bikes to be ridden.

This year, the Dogtooth Dash began a day early with a vertical race. Having sat out the vertical race at world championships last year, this would be my first crack at the format that favours efficiency and power rather than technique and fearlessness (other than laying it on the line!)

The race started with the usual mad dash on some appropriately angled terrain, then the course hit a steep wall! I was actually doing quite well here, relying on skinning technique (keeping those skis flat on the snow rather than edging), getting in a good rhythm and being able to go max out JUST to get up the hill! Then as the course crested onto the 10 road cat track, the angle lessened and classical diagonal stride technique became very important. I broke the instep buckle rivet on my boot trying to get a good kick and glide going. I put in a strong effort, and had a really good sprint in the run towards the finish, but lost some ground on the flatter sections. Looks like I'll have to spend some time on the classic sticks next winter. Roller skis? Mmmmmmaybe...

Nice and sunny at the finish.
The next day was the main event. I felt like I had recovered well from the vertical race the day before but a hard effort had taken the very top end out of my legs. This actually led me to race with a different strategy, rather than starting out hard and blowing up, I would just race at a reasonable pace. Now I'm a big believer in the slingshot effect of getting a good start and then recovering, but oh well, let's give this one a go!
I was feeling good and sitting well but suffered on the leadup to the tunnel vision bootpack roughly halfway into the race. After having the race of my life and finishing 3rd last year in just another highlight of a wonderful season, I was in tough shape. My mind was tormented with thoughts of self doubt, emotion from an event that happened the previous weekend, that had me really questioning why I had been burning vacation days, weekends, and dinosaur turds to head to these races. Then on the next climb I looked up and could see that the battle for 3rd place was not too far ahead and I was just a skin failure (not unrealistic with dry snowy conditions and lots of transitions) or blowup away from really being in race. I'll take that as a consolation prize for this Weekend Warrior.

With a flawless transition and excellent skiing on the last descent, I really lit a match under the wick of those in front of me and I was ready to battle for the next couple of spots. I didn't have much left to make the catch, but I was happy with that.
So yeah, definitely feel like there is some work to do to get back to the level that I think I can race at: I've got to get more intimate with staircases and XC skis.

A couple of weeks later was the Vert 180, rescheduled after being postponed in December due to cold weather. Normally this race is a great time to work on transitions and get 3hrs of hard effort to kick off the season. Now moved to the end of the season, where my mind was craving spring skiing and rest and I had no reason to practice transition skills that I would not need for 9 months, I was not terribly motivated.

But with the sun shining, soft snow, and my sleeves rolled up, I actually enjoyed racing on last time this season. We bombed down the slalom pitch which got icier and icier as the night progressed. I settled into 2nd position. Travis was untouchable, not even a broken boot cable and stopping to fetch a Voile strap could allow me to reel him in. The course got faster as the night approached and the snow froze. I felt like I was able to maintain a good cadence the whole time and so I can say that I had a lot more fun than I thought that I would have.

So a great season capped off. I've got my work cut out for me if I want to hang with the lead group next year!
