I'm currently racing in the PIR short track XC series, which is my first MTB racing of the year.
The reason this is the first XC races I've done this year...I don't like to ride in mud which is very prevalent in the spring. Also the road race season is in full swing during the spring which is when many of the single day road races take place.
I was really looking forward to racing some of XC races this year until I looked at the schedule and noticed almost all races were in the spring when the weather is horrible in Oregon. That pretty much changed my mind until the Short Track XC races at PIR came around.
For me the spring is single day road races and Time Trials. Summer is XC racing, stage racing (road) and crits (road).
It's unfortunate that either the racers only want to race in the spring or the promoters only want to race in the spring (one of the two parties (racers/promoters) isn't listening to the other side) as I won't race MTB in the spring...Those races are more about survival than who is the best rider.
I love to ride and race MTB's (it's what got me on a bike many years ago) but with the current schedule...I won't be joining the XC race series any time soon.
