Racing with the PT attached.
Hi All
Well, the racing season is back again! Just wondered if any of the coaches here would recommend using the PowerTap while racing. I’ve got a rest week in a couple of weeks with a race at the end of it. I’m wondering if it’s worth using the race to find some of my critical powers in a racing situation e.g. 5sec, 5 min, and the average power needed for a race. Are these values good as indicators when completed in a race environment? Cheers Chris |

hi chris, it's well worth using in your races. i used mine in all my races. helps you to understand what's happening in a race and where you maybe deficient (e.g., uphill). also, good for helping you to pace yourself if you're off the front. and good for motivation too. cheers ric

Thanks Ric I was thinking it would be good thing... I raced at the weekend and did some hard efforts. It really puts things into context. I may do it for my lower priority races to see where I'm weaker. Its just a shame the wheel weights about the same as the rest of my race bike put together! Just to let you know I've been doing those tempo workouts you mentioned on here a few times (up to 90mins @ 80-87%MAP). They seem to be working well as my base 'engine' seems to be good and I'm finding e12 races very comfortable at the moment...even without any kind of intense training (and being 8kg over rac weight).

As i know where you are located, and knowing that it's unlikely that you're racing over climbs that are > 5-mins and that you're over race weight, the extra ~150 g of the PT isn't going to make any difference! In fact rather than hindering you, i (and riders i coach) find it's advantageous as it enables you to not go too hard at (e.g.) the start of a climb. the main disadvantage is if you have the hub laced to a non-aero rim, as at velocities > 20 km/hr air drag is the biggest retarding factor. I don't think you mean 80 - 87% MAP for 90-mins as that would be impossible for anyone! maybe of TT power! cheers ric

Ooops your right ...
I did mean TT power! HA I wish I could avarage 80-87MAP!! Roll on Hour Record  Yep, I see what you mean about the PT... Im just being stupid... Im going to fit it to the racing bike, that way I dont need a bike computer either! Cheers Chris |

:-). Mind you, even if i could ride at 100% MAP for 60-mins i wouldn't beat the Hour Record! :-(. Such is the quality of Boardman and the other pros! On the wheel front, i can see three options 1) keep the wheel as is and use for racing and training 2) if you haven't already (?) fit an aero or semi-aero deep section rim (i have a 30-mm rim), and when i get my wheel rebuilt will have it laced with aero spokes that don't require the hub to be slotted such as sapim CX-Ray 3) get a spare hub and have one on a nice aero rim, and use the other for training Cheers ric

chris,
ric touched on the subject of pacing when off the front. this is a great device for any athlete to stay within their limits. andy coggan has also noted in his papers that the pros do two things. 1. a whole lot of drafting (use your power meter to reassure you are conserving energy) 2. and going hard when it counts (use the power meter to log your max efforts and average watts during these times in the race to identify your capabilities). personally, i don't recommend looking at the numbers during this time of the race. it is best focusing on the race and not get psyched out by seeing watts that you may not normally see during training. i wouldn't worry about an aero wheel unless you are doing tts. use the field to draft... good luck this season, velosmartcoach |

That's True.. I spend as much time as possible off the front ;o) ...and you can always do with a bit or aero help whereever you are! Ive just realised Im on 10speed on the racing bike... so thats a bit of a bugger! Looks like I'll have to race on the training bike... or upgrade the training bike to 10sp... hmmm expensive! |

i don't want to state the obvious, but why not put a 10-speed cassette on the PT for your racing bike? ric

It is the easiest solution... but Its just a pain when im racing 3 times a week and training the other 3 days to keep swapping them over... I live in a flat so the back bedroom is turning into a workshop... hmm... does the 10sp block have the same spacing as the 9sp? |

not sure? i use 9speed. i'm old fashioned!!! maybe if some of those races aren't important (low priority) you could do them on your training bike. Or train on your race bike (which is what i do). ric

While I'd like to take credit for such observations, I think you're referring to data that have been presented by Asker Jeukendrup (showing an average power of <100 W for a rider during a flat TdF stage) and by Dave Martin et al. from the AIS (showing that the female cyclists who tend to be most successful in WC road races spend more time producing power at the extremes, i.e, either very high or very low). |
