Training objective: nice tempo ride for 3-4 hours with the heart rate at 140-150 bpm's and the cadence between 70-80 rpm's. Spent the first 50 minutes faffing about - all below objective (headed over to WV Amsterdam to see if I could pick up my club kit, but they were closed by the time I got there). Finally got out of the city and got going, so hit the split/lap button to demarcate the start of some "proper" training and getting reacquainted with the new 11/32 cassette (I definitely prefer the 11/28 for training and might even move to something more like an 11/25 for long, flat rides and more power training in the Fall). I did an earlier ride in the day on my "Oumafiets"" going out to pick up my race bike and cycling back with it beside me. About 18 km's - that was a decent pace (2 Strava PR's on the old clunker - ha!) and hard work. Threw in a few sprints for good measure on this ride - had quite a bit of wind against this circuit. Then, at about km 92, two mallard ducks launched themselves out of the bushes and into my front wheel (while I was doing 36 km/hr). Fortunately, I stayed up. Unfortunately for them, well, I suspect they're rather injured at best. Sorry ducks!!! When I got back to the bike storage place, I noticed I still had duck down caught in my spokes...
