Going to Ballinastoe the last two months now, no matter what trails I'm doing I'm pretty much done after about 60-70 minutes of cycling time.
I start with the first few blue trails then take the gravel road up to Zipper, then a red trail back to the blue loop to finish at the car park. Going once or twice a week, I was hoping I'd be fit enough to do a second lap of the red but the climb back up from the Expressway area just kills me.
I have a base level of fitness but having a big gut these days certainly doesn't help. I think one of the issues is my mind sees the trails down as a break from the climbing but they can be physical in their own way and when I'm done I'm back to climbing the gravel roads.
It probably also doesn't help there isn't really many places to sit and take a minute, other than just taking a minute before going down trial. I think another issue is my 'lap' is too long to do a second, rather than go back to the bottom and start another lap I should do a red trail and immediately go back up for another, then finish the loop.
Any tips on how to spend a bit more time on the trails? There's times at the 10% climbs that I'm walking the bike and feel like I'm giving 110% just to get back to the hill. On the road bike people would say only increase the distance by 10% when building up but mountain biking is a bit trickier as there's only so many ways to get around between trails, you're inevitably going to be adding a chunk of climbing if you want to get that extra trail in.
