I've been snowboarding for about 11 years (average 2 times a week during the season) and I have recently started doing boardercross. The courses seem really icy and its hard for me to hold an edge through the turns. I am really strong at the start and through rollers but once the turns start coming i start to lose speed even when i feel like I am making a good turn. I havnt really tuned my board in like a year but I dont really think that is responsible for the 4 second delay i have on some people down a 40 second course. I am a really advanced boarder but carrying my speed through turns and keeping my edge seems impossible.
