Xc Ski Racing Plus
XC SKI RACING PLUS XC ski racing is fun… right? Well, what about ski racing with your brain turned on? That’s ski orienteering! What’s the difference? In xc skiing, the course is marked to tell you where to go – just apply the horsepower. In Ski-O, you still have to apply the horsepower, but you have to decide where to go while doing it. How does it work? At the start, you’re given a map of your course, like the map shown here. The pink circles represent control points that you must visit, in the right order, as fast as you can. The solid lines are wide, skateable trails, and dashed lines are narrower trails where you can only double pole. Knowing your relative strength as a skier affects your route choices – how would YOU go from #10 to #11 on this map? What do you do at the controls? At each control, there is a flag to mark the spot. To record that you’ve been there, you “punch” with an electronic recording device, worn on your finger. It makes a beep, and when you finish, the officials download the data from your finger stick and give you instant Equipment: results and your splits between all To carry your map, you use a map holder that mounts to controls. your chest, so that the map is always right in front of you, and can be rotated to align it with the direction you’re skiing. Races are freestyle, so most skiers use race skate skis. Poles are modified to have larger baskets to deal with the soft snow on narrow trails. -

Trail running is a sport where participants run different distances on trails in nature. According to International Trail Running Association (I-TRA), “trail running is a pedestrian race in a natural environment with minimal possible paved or asphalt road. The amount of roads should not exceed 20% of the distance.”1 However, recreational running on trails also fits in to the definition. -

Physiological Determinants of Ultramarathon Trail-Running Performance
International Journal of Sports Physiology and Performance, (Ahead of Print) https://doi.org/10.1123/ijspp.2020-0766 © 2021 Human Kinetics, Inc. ORIGINAL INVESTIGATION Physiological Determinants of Ultramarathon Trail-Running Performance Alexandra M. Coates, Jordan A. Berard, Trevor J. King, and Jamie F. Burr Context: The physiological determinants of ultramarathon success have rarely been assessed and likely differ in their contributions to performance as race distance increases. Purpose: To examine predictors of performance in athletes who completed either a 50-, 80-, or 160-km trail race over a 20-km loop course on the same day. Methods: Measures of running history, aerobic fitness, running economy, body mass loss, hematocrit alterations, age, and cardiovascular health were examined in relation to race-day performance. Performance was defined as the percentage difference from the winning time at a given race distance, with 0% representing the fastest possible time. Results: In the 50-km race, training volumes, cardiovascular health, aerobic fitness, and a greater loss of body mass during the race were all related to better performance (all P < .05). Using multiple linear regression, peak velocity achieved in the maximal oxygen uptake test (β = −11.7, P = .002) and baseline blood pressure (β =3.1,P = .007) were the best performance predictors for the men’s 50-km race (r =.98,r2 = .96, P < .001), while peak velocity achieved in the maximal oxygen uptake test (β = −13.6, P = .001) and loss of body mass (β =12.8,P = .03) were the best predictors for women (r = .94, r2 = .87, P =.001).Inthe 80-km race, only peak velocity achieved in the maximal oxygen uptake test predicted performance (β = −20.3, r = .88, r2 = .78, P < .001). -

The Hammpions
2019 Relay Team Profile: The Hammpions For two brothers from a family that loves running, the opportunity has finally arrived to team up as a duo for a popular long-distance relay race. Later this month, John and Paul Crowe will run the 50 miles of the Tussey mOUnTaiNBACK 50 Mile Relay and Ultramarathon as a two-person relay team. Both grew up in State College. John Crowe now lives in Pittsburgh and Paul Crowe lives in Milford, NJ. “This is our first time doing the Mountainback,” said John Crowe. “Our dad has always been involved in some capacity, whether hosting runners or competing on teams, so it has always been on our radar.” It’s pretty well known in the local running community that Crowes are not the type to shrink from a challenge. Their father, Rob Crowe, has run numerous races over the years, including the Boston Marathon, and still actively races in the local community. Their mother, Sue, was a standout runner, including multiple wins at the Nittany Valley Arts Festival race. But this kind of race is often out of bounds for students who run for cross country or track teams. “Unfortunately we never had the opportunity to participate in it while we were in high school and college,” said John Crowe. “Now that we are both trying to get back into running competitively again, this seemed like the perfect race to do together.” The course’s 12 segments on the roads of Rothrock State Forest are of unequal length and difficulty, so when these two runners switch back and forth to run every other segment, one will run a total of about 22 and the other about 28 miles. -
MTBO Annual – 2015 Editorial
MTBO annual – 2015 Editorial Welcome to The Australian Orienteer’s MTBO Annual for 2015. This publication is a compilation of the MTBO stories that have appeared in The Australian Orienteer during 2015. We’ve added a couple of extra stories – an interview with Alex Randall from the December 2014 issue, and also an updated mapboards article. We’ve made this available as a PDF file so that any keen MTBOers who do not subscribe to the magazine can see the articles they missed out on and perhaps decide to take a subscription. We hope you enjoy. Peter Cusworth Cover: Angus Robinson, Gold medallist in the M20 Sprint at the World MTBO Championships in Czech Rebublic. Photo courtesy of WMTBOC 2015, Ivo Habán.

A key goal here was to bring MTBO in line with Foot O and Ski O. This seems a good idea in the large classes such as M40, M50 and M60, but will make others, particularly the Women’s classes, look a bit thin. The Council did not support a proposal to merge classes if there are fewer than 10 participants in a category, opting for a consistent rule across The first start group gets underway in the Summer 75 MTBO evening event at all classes and disciplines. -

Advice to Competitors Regarding Footwear, Gaiters & Clothing
Advice to Competitors Regarding Footwear, Gaiters & Clothing The advice is being provided to assist Competitors in 14WRC2016 choose their footwear, gaiters and clothing for the event. There are two key aspects of the terrain for this event which are quite different from many other rogaines with regard to the choice of equipment and particularly footwear and gaiters. These aspects are (i) Spinifex and (ii) the very rocky terrain. Spinifex Spinifex (Triodia species) is a tough, spiky tussock grass that dominates much of the red sand desert and rocky ranges of Central Australia. There are 64 species of Spinifex in Australia and 34 are found in the Northern Territory. However, in practical terms to a competitor in 14WRC2016 there are effectively two types of Spinifex on the course. There is the Spinifex that grows on the sandstone based soils which is quite tough and spiky and then there is the Spinifex which grows on the limestone based soils which is much tougher and much spikier. There are far greater areas of the “limestone” Spinifex on the course that there are of the “sandstone” Spinifex. Of course considerable areas of the course have little or no Spinifex and we will provide some indication where on the course the “heavy” Spinifex is. However, there is a reality that competitors who do not have footwear and gaiters suitable to deal with Spinifex will have an extremely uncomfortable event! Typical Spinifex Area Page 1 of 4 Spinifex Covered Hillside – A Common Sight on Parts of the WRC Course For people who have not experienced Spinifex before it is difficult to describe how challenging and painful it can be if you have inappropriate footwear and gaiters.
