The main discussion on the Training and Nutrition forum over the last month has been the Mount Haleakala hill climb in Hawaii, which is a 55 km ride to an altitude of 3050 m (5.5% average grade). The forum discussion briefly mentioned the challenges of exercising at altitude and the possibility of using altitude training to prepare for travel to a high-altitude environment. As an Accredited Sports Scientist and operator of Adelaide Human Performance, I thought I’d provide some background about altitude training.
Any discussion of altitude training needs to start with the metabolic role of oxygen and how oxygen availability decreases at altitude. The oxygen we breathe is used by the aerobic metabolic pathways to synthesize energy for cellular work. So in terms of exercise capacity, the more oxygen we can consume, the more energy that can be produced, and the more work that can be performed. This is why…Continue
Her transformation of New York from gridlock to a walkable and cycle-able city is legendary. Velo-City guest speaker Jannette Sadik-Kahn was New York City’s Commissioner of Transportation and oversaw its dramatic transformation to a cycling and pedestrian mecca, and her presentation impressed Bicycle Institute's Gus Kingston.
Great mountain bike ride few weekends ago. starting from Mt Crawford Forest HQ. Rode around Mt Crawford from the south and, perhaps illegally, crossed some land to get to Police Paddock rd which takes you thru the Gap. Council Maps web page shows a public access route, but couldnt find a visible track. Onto Mount Rd and up the lovely fire tracks in Wirra Wirra peaks. Lucky to have my map to find the less steep parts. Onto Blockers rd for a hard slog on the Heysen trail linking up to Ross Fire track. Down Old Glen Gillian rd. On the main rd. Turn up Manser rd , into Forest following Fry road leading back to Mt Crawford Forest HQ. Probably avoid the Blockers rd bit next time.
Earlier in this year (in March) I embarked on a big tour of Norway and Finland to go chasing the Aurora Borealis (aka ‘The Northern Lights’)
I had a couple of days in Stockholm (Sweden) and a couple more in Copenhagen (Denmark) and for the benefit of some cycling friends here in Adelaide I have collated a few photos to help de-mystify the Scandinavian bike thing.
Unlike my great trip a few years ago where I hired a bike and rode around Manhattan my experiences of this trip were limited to being an observer as foot traffic and occasional taxi rides. Sounds like a cop out but considering my grand stuff up from Feb 2013 (I broke my leg slipping on ice in St Petersburg on day 2 of a 6 week holiday!), my notion of risk was highly elevated and jumping on a bike was ruled…Continue
