I don't particularly like charities, but I have granted money to a few of my student employees who I knew were struggling with one thing or another. It's very minimal and I see much of my younger self in them, as well as just have a lot of gratitude for the work they do for me. If we ever inherit some fortune I'll probably take care of my mother and brother and retire or work somewhere I might actually enjoy.

Drove to the gym to coach last night instead of riding. On the way home in the dark there was a cyclist drafting a car in front of me at almost 40 mph for quite a long time.

I'm too lazy to read the entire TT thread sticky... how much faster is a true TT bike vs road bike w clip-ons? 5 mile, rolling TT.

Making a kilometer blurry
Holy cow, aerodynamics makes a huge difference.
Going from a standard bike to a tri position with aero bars saved a whopping 10% right there. Given that you were like, 3 minutes behind the leader, I'd say you have a very good chance if you had the right position and equipment.
I ripped this off of someone else who ripped it off of someone else who translated this month's issue of Tour magazine.
They put Uwe Peschel on a normal bike:
Needed Watts for Speed = 45 km/h :
Stevens San Remo bike with normal handlebar 465 Watts needed to go 45 km/h
Same bike Hands down the drops: 406 watts needed
Same bikeEaston Aeroforce bar: 369 Watts
Same bike Triathlon position (5.5 cm lower bar, saddle forwards): 360 Watts
Same bike Triathlon position (5.5 cm lower bar, saddle forwards) and
carbon Tri spoke wheels front and rear: 345 Watt
Cervelo + Tri spoke front 328 Watts
Cervelo + Tri spoke front + disk rear wheel : 320
Cervelo + Tri spoke front + disk rear wheel +Giro helmet: 317
Cervelo + Tri spoke front + disk rear wheel +Giro helmet + speed suit: 307
Cervelo + Tri spoke front + disk rear wheel +Giro helmet + speed suit +
saddle 3 cm further back: 293 Watts
From 465 to 293 watts... That's a lotta savings.

I would like to see a test to see if there is any advantage of resting forearms on the bars in the time trial position while on a road bike. I do this sometimes when I'm on flat ground and know I won't need to brake or shift immediately. I noticed a lot of the guys in the tour did this when they were off the front. I'm not sure if they were doing it to change body position since they are on the bike for hours at a time, or if it's beneficial to conserving energy.
The position on the bike is the same as being in the drops with elbows bent, but perhaps since the arms are out in front and close together and not holding the drops, maybe there are some energy savings.

I suspect it depends on the rider but I am just another random internet opinion

Shovelhd, great news on the ocular health front there!
But in that photo, they're bent ~45 degrees. Tiny frame, long and flat stem, low-rise headset. His back is pretty low, but not flat. Maybe 15 degrees up from the guardrail/road parallel.

anyone here deal with arthritis? i'm a bit past my first full season of riding and am dealing with some increased arthritic pain in both index fingers. it's really picked up over the last month or so.
edit: currently use Force, perhaps di2 is in the future.

I use the Fizik gel pads under the tape. Works great.
Coming off the front of the chase with a really nasty crosswind from the left. In those situations I push my forearms against the inside of the hoods for stability. It still feels faster than in the drops. I can also shift by banging the sprint shifters.
