You did pretty dam good to get the tamdem thru those conditions.
I rode out to Waterfall with Dulwich Hill. Eventually the quick guys in our group tacked on to one of the Eastern Suburbs groups as we headed for Waterfall. A guy about 3 bikes in front of me got a flat front tyre and everyone had to heave on the brakes. So we arrived at Waterfall and did u-turn over the bridge, when back on the Princess, the pace was about to up for the sprint back to Heathcoat. Being a little slower than the younger guys, I speeded up and went to the front, 3 guys went blasting past me at a pace well past my ability, I was waiting for the bunch to catch me so I could tack on, but then the bunch caught me napping, they were going so much faster than me, that I didn't get myself up to speed to tack on. I chased for about 2k but I couldn't close the final 50 metres, they were setting a wicked pace. No one came past me or tacked on, so I had no one to share the work, so I gave up. About this time the pack started sheding riders, I passed a few and then one tacked on, we worked together and collected another 3 and had some fun riding into Heatcoat. But man there was someone really fast on the front of that pack, this vet was no threat to him!
Stanmore do a hill ride on the first Saturday of the month, ie this Saturday coming up, they leave Stanmore cycles at 5.30am and head over the north side. At the top of each hill the stop and wait for everyone to catch up. Suitable for everyone, fast or slow.
