I’m kind of hoping the lap times set at frith hill in the morning were in very different conditions to those of the afternoon, or something has gone badly wrong in my riding (but thats not unlikely)!
As for the dropping a category thing, this is my first year of xc racing so I’m not qualified to really comment on others, but I picked the Open cat and have stuck with it as I thought it would be better to track progress. Others seem to move between close categories, like open and sport, depending on the series. My observation seems to be that this is based on where they will get the best race with similar level riders, rather than anything sinister, and the variable level of the categories at different events would seem to make that approach a good idea, more so maybe than my approach in terms of consistent races!
Really enjoying the local xc series’ and +1 for the impressive riding skill of the good guys, on top of the fitness. Events like the xc Rampage, with no hills, really made it painfully obvious that fitness alone won’t get you up there!
