YMCA, thanks for that insightful post. Thinking about heading over there to race has really stoked my fire to train. If you do decide to head over and be a mentor, which from your posting you would be great at let me know!
I've been doing weekly maintenance threshold intervals at around 15'-20' and will be starting to build those up in frequency this month so that should dovetail well with the belgian requirements. Threshold is my weakness as a sprinter so my goal is and has been to train that weakness.
We have some good flat to rolling road races out here that are on the plains east of Denver that typically have high winds and consequently always turn into gutterfests so I'm fairly familiar with the crosswind dynamics although I'm sure it's more extreme across the pond to the east.
