Pre-breakfast training

I did one of my regular short fitness ride this morning before breakfast on my carbon Giant Defy. The difference is amazing, compared with my trusty hybrid. I did the ride in 31 minutes rather than the 40 or so I normally take. The tyres are rather narrow (23mm) for some of the road surfaces round here and I’m wondering if I could do with a more utility road bike in my stable. The Ridgeback hybrid is very heavy but I wouldn’t dream of parting with it. It makes a great commuting bike and of course, being heavy, it gives me plenty of exercise too!
