    Time Trial

    On Saturday, we completed our first time trial on our tandem since returning to cycling in May 2006. The results are posted in http://www.scaledup.com/beattheclock/2_07_overall.pdf. There were 49 entries and we are team Genentech. We completed the 9.7 mile course with an elevation gain of 400 feet in 28 minutes and 45 seconds. At the morning of the TT, our team weighed 284.4 pounds and the bike, as raced, weighed 35.4 pounds (weighed at bike shop). Below is an elevation map of the course.



    The race was fun and we had beautiful sunny, clear weather. The temperature was in the low 50s when we started. The people who organized the event did a great job and the proceeds went to charity. We rode the flat and downhill sections of the course at approximately 90% max HR and the hills at >95% max HR. For the last mile which was uphill, we were rode at max output. For an early season event, we were happy with the effort. If you are not familiar the time trial format, riders go out on the course a minute apart and race against the clock. We plan to ride the next time trial, March 28th organized by the same people. We are deciding if it will be tandem or individual. Most of the riders in the event had aero equipment including TT bikes, TT helmets and TT wheel sets.

    After the TT, we rode another 30 miles and saw a number of pro cycling teams on the road training for the Tour of California. It is really cool to see the pros on the road where we ride.

    On Sunday, we rode 30 miles on road bikes and in the afternoon, we went to San Francisco to see the Prolog (1.9 mile time trial) of the Tour of California Pro Bike Race. It was a beautiful day for cycling and we walked around the area where the pros stage to warm up and you can see the pros, hardware and take pics. Also, we watched the pros as they started and also on the course. The access to the riders and the equipment was excellent. The amount of hardware and support for each pro team is amazing.

    We were off on Monday and went on a 54 mile tandem ride. We had beautiful sunny weather with the temperature in the mid 60s.

    Would loved to have seen you in Santa Rosa. Groups started out on the course and road into town. They timed it so they got into town after the course was closed and did loops on the 5 Km loop in town. There were several tandems. You could loop until the pros were 4 minutes outside of town.

    Did you have one or two starters holding the tandem at the start line?
    Was it an out and back ride? How tight was the U-turn at the turn around?
    20-some years ago we did time trials on our tandem. Starters were puzzled on how to hold us up for the start . .
    On one 20-mile TT we had a much younger tandem team (we were in our 50s, they were in their 20s) start 1 minute behind us and they were gaining. At the tight turn-around we made the U-turn with about 2 inches of pavement to spare; they, however, ended up in the dirt and we gained our time back.
    Must say we were riding a very short wheelbase tandem at that time (60 1/4" wheelbase) which really facilitated the turn around.
    Nice to see that you did it on your tandem. Congrats to pilot/stoker!

    There was one starter holding us and he did a good job such that we were both cleated in .

    It was an out an back course with the predominant downhill going out and mostly climbing on the way back. We practiced the start and turn around to make sure we would be in the right gear and how to come in fast to the turn around, brake, turn, shift and accelerate. The course was a two lane highway with wide bike lanes on both sides. It was not a problem for a tandem to make the turn.

    You two did great on your first Tandem Time Trial (TTT)! Sounds like your pre-TTT practice paid off.
    When we had to make our U-turn turnaround it was on a narrow (no bike lanes) frontage road.
    Only once did we have 2 starters holding us. Not really an issue with an experienced starter.
    Do it again!
