So it slows me down going down hill How do you quanitfy 50g of drag? It is a rare occasion, if ever, I am doing 25 mph on the flats. that would also have to be compared to the drag caused by me moving my arm to untuck/retuck the straw
50g drag = 5 w = .5s/km so....on a HIM 45sec And interestingly, a torpedo bottle setup actually reduces drag by about the same amount, compared to no bottle at all, because it fills in the area between your arms and decreases turbulence. Oops I might be geeking again. |

Oops I might be geeking again. the A2 is set up torpedo style, so that's a wash? So adding in the reduction in drag by not moving my arm to remove the straw, I am faster with the straw up.

Yeah I've been riding with a regular bottle for awhile now. Avatar photo is kinda old. So I reduce drag there and reduce it with the P4 bottle. It's like cheating! |

Veteran 2842 Austin, Texas | Subject: RE: SBR Utopia - OPEN spudone - 2013-04-23 5:17 PM It is hard to test. How do you test the ability to generate power ? Do you make him do a 20' power test, change his position, do a 20' test ? Do you look at his HR at a given power level ? Do you go by RPE ? They all have their flaws. If you're testing ability to generate power, then yeah, you need a 20' test at threshold. A simple CdA test, though, you can ride, say 5 mins at a fixed power level and see what your average speed was. Or flip it around: ride 5 mins at 20mph (or whatever) and check your average power. Preferably in a velodrome or non-windy, flat out-and-back. There's more detail in Training and Racing with a Power Meter, pg. 249-252ish.

/end geek Are you suggesting I actually READ a book I've purchased? A bit over the top, sir. |

Payson, AZ | Subject: RE: SBR Utopia - OPEN OMG TrainerRoad is at it again. Must be strong and refuse to get involved.
What is "8 Days in California"?
8 Days in California simulates what an 8 day stage race might be like in California through TrainerRoad.com's software. Workouts will simulate a live race with a story overarching the entire event. Riders will be challenged to cover breaks, bring up water bottles and protect their team's GC contender. The challenge will consist of 8 workouts over 8 days. Workouts will last between one and two hours. There will be flat stages, mountain climbs and even a time trial. Riders who successfully complete the challenge and do their duties to the team will receive a coveted 8 Days in California badge on their career page. The workouts for 8 Days in California will be announced one week before it starts (May 5th, 2013). We will release each day's workout the night before it happens.

Almost had that happen at Poconos. The bike was cruising along, but not that fast on a slight downhill. I came up, but they couldn't hear me with the full helmets and motor going. Ended up getting around ok. Passed them on the right too. |

Master 10208 Northern IL | Subject: RE: SBR Utopia - OPEN Interesting run today. On the treadmill, I've been doing threshold hill intervals recently and tried cranking up the intensity and moved spacing to VO2 pattern. I had to increase speed more to go from threshold to VO2 on the uphill than when I did similar workouts on the flats. Would have thought it'd be smaller with the slower speed? The whole workout was noticeably easier than I thought it was going to be. Did the last one flat & fast, and again it wasn't really hard (for this type of workout). Speed was limited more by coordination than effort. This is great, but also weird at the same time. |

Subject: RE: SBR Utopia - OPEN Fred D - 2013-04-23 1:36 PM axteraa - 2013-04-23 1:36 PM . I targeted about 215-220w for the same race. I was definitely at 300w for some climbs and people flew by me, then again they didn't stay ahead for very long. Honestly that was one definite positive of using power in the past.... Helped me give more even efforts on climbs which is smart in long course triathlon racing. ChrisM - 2013-04-23 2:14 PM Two weeks will be the first time I am racing with power, and it is on a tough hilly course (Wildflower Oly). Last time I raced the WF long course, my coach at the time basically told me to leave the HR monitor at home, because it would just be too frustrating trying to stick to zones on such a difficult course. We'll see what happens in two weeks, I guess. The CT is incredible for training, as I am sure a PM on a trainer would be. I can't imagine going back and training on a trainer with just HR. It can be really difficult (if not impossible) to stay within power zones on hilly courses. My target power for IMMT was 175 but on many of the hills I had to go over 300 just to avoid tipping over. However, on other hills where I could manage, it was great for keeping me from being too aggressive on some hills. It can be REALLY hard to cruise up a hill and have a boatload of people passing you. The first loop around I quickly discovered that I would repass many of those same people as they coasted and tried to recover on the descents. Yeah...most of the local races I do here are pretty flat for the most part so you don't see too many people overcooking hills. At Honu there are a lot more rollers...and even though I have not used a PM there yet, I had an idea through training of how to manage my effort by shifting accordingly. I saw so many people jump out of the saddle to crest the rollers without shifting. I know the field at Honu is must stronger than my local races, but I was surprised at how many people were passing me during the first 15 miles of the bike. But then again, Honu is the only race I've done where I actually pass people on the run. And not because I run fast...because so many people are already walking within the first 4 miles. |
