Jim Barron at Dirt Vixens

January 08, 2015

Director of Dirt Vixens & MTBSkilz Mountain Bike Skills Companies

Level 2 MTB Coach, Instructor and Guide


Jim is a very experienced instructor and has many years of mountain biking experience.  He bought his first mountain bike in 1987 and was soon competing on the racing circuit at Elite level. Having taken a break from the sport for a few years in the mid 1990's he founded the Moray Mountain Bike Club in 2002 and was part of the team that developed and built the Moray Monster Trails.

Although still competing in some endurance races Jim found that he was enjoying pushing the limits of his skills more and more, as a result he has ridden extensively abroad.  He is also involved in promoting and hosting races through his involvement with No Fuss Events.

Prior to undertaking formal qualification Jim had been encouraging and developing mountain bike riders since 2002.  He now holds the highest level Mountain Bike Leader Association qualification of Mountain Bike Leader (MBL), together with the Night Leader & Winter Leader Modules.  He is qualified as a Go Mountain Bike Instructor with Cycling Scotland and delivers skills training to the highest level - Level 5. Jim is also a British Cycling Level 2 Coach and holds the Level 2 MTB discipline specific unit.

Several years ago Jim set up Dirt Vixens, a female specific mountain bike skills training company, having identified that there were many female riders out there who were not able to develop their riding in the manner that they wanted. He found that some female bikers were reluctant to attend mixed group skills development sessions.  There seemed to be many reasons for this but the main one appeared to be that many women are more comfortable developing their skills within a similar peer group.  So Dirt Vixens was formed with the aim catering for female mountain bikers of any level who wanted to improve their riding.  Whether they were new to the sport and wanted to learn good technique from the start, or had been riding for a while but wanted to up the level of their technical skills.

“Buying the right mountain bike” is the first in a series of articles that Jim will be writing for us. This first article obviously deals with the purchase of a bike, but future articles will focus on various core and technical riding skills and will be published on a monthly basis.
