Gjermund Sørstad

Gjermund is an active ultra runner on a high level, nationally in Norway as well as  internationally.

When growing up, he was active within football (soccer) and ski jumping. At that time he was not interested in running. When being diagnosed with migrene as a teenager, he needed medication that made cardio training very heavy for him, so he had to quit sports for a while. After getting new medicines, he started over again with football. To be able to increase his general physical condition and capacity in order to complete football matches, he started running.   After having done this for a while, including completing a half marathon and a 10 km, he entered a local track & field sports club at the age of 18, and stopped playing football actively. The club provided a good training environment for him, and after two years of training with the club, he cut  his half marathon time with 15 min and made his debut in marathon.

At the age of 23 he run the marathon at 2.39, and a couple of years later he made his debut in a 100 km race. An ultra runner was born. However, it took 3 more years before he seriously entered into the ranks of the ultra runners.  For several years he was very diverse in his approach to training. He participated in triathlon, set a world record on marathon on a rowing machine (!),  competed in cross country skiing and was also active on the bicycle for a while.

In 2007 he went deeper into marathon and ultra running, increased his mileage significantly, invested in a treadmill at home, and it didn’t take long time before the results improved significantly.

Some selected results:

– Winner of St.Olav Ultra 2008 (National competition between Norway an Sweden)
– Winner of St. Olav Ultra 2010.
– Winner of Espoo 24 hours in Finland in 2010.
– Norwegian and Nordic record in 12 hours. 147,9 km (2011).
– Winner in Karlstad, Sweden, 6 hours indoor, 2011. 84995 meters (Norwegian indoor record for 6 hours)
– Number 11 in the World Championship and number 9 in  the European Championship in 24 hours run in Katowice, Poland 2012.
– Honoured as the Ultra Runner of the Year in Norway in 2010 and 2011.

Gjermund is educated as a child welfare officer and works as a local community consultant for children and youth, besides being a freelance journalist.

Bjørn Ross

Bjørn is the founder and editor of World Wide Runner.

Bjørn has always been interested in and practised different sports activities, and “discovered” running a few years ago. During the first years of running, being a little bit too eager on progress, while still being a bit overweight, running injuries came one by one … Name the most common ones, and Bjørn have tried it. Shins plints (who hasn’t tried that?), hamstrings rupture, jumper’s knee, achilles inflammation…..

It was in the search for information about these injuries, for good training programs and for running routes when travelling, the idea of this site was born. This because  little detailed information was available without having to pay quite a lot of money as a premium member for different apps and websites, or the information was fragmented throughout different sites and apps.

Bjørn has participated in 10 km and half marathon races, but the results are not really worth mentioning here…. However, they are continuously improving, and the long term goal is 1,45 for the half marathon.

He has a Master Degree within  mechanical engineering and runs a consultancy business within project management and quality management.
