Expert  1027   Zürich, Switzerland |  Subject: My cycling performances: what do you think?I need some suggestions and thoughts from your cycling expertise. Since running and swimming are sports where you can have a track of improvements, cycling is quite though to judge for me and I am new in this sport. I do 4 or 5 sessions per week and I am training for IM and HIM. I have an indoor trainer where I do 3 sessions and 1 long outside in the week end. I find the trainer quite useful for IT training where I can push 85% of HRmax for several times, depending on the day. The main question for me is related to HR vs. Cadence/Speed. I find very difficult to raise my HR on the bike while, as a runner, I can do easily all the planned session pushing up to 99% on 3k racing on track and field. Some numbers now for letting you understanding. Today I did 2 sets of 18'00@75% HRmax + 9'00@85% HRmax Unfortunately I did not do any LT test on the bike but I have 169bpm on 10k running race and an estimated 184 HRmax on running. For semplicity I assume 10bpm less on the bike. Today for rising the HR to 85% I had to use the 52crank and the 12 behind (I have a triple 12-27 ultegra) so the strongest combination. I have set the trainer resistance to match exactly a flat road. Recorded data were, on the last 9' session: 87rpm, 136bpm average, 42.3Km/h average If I have to push more for having 85% average (around 145bpm), what about when I have to push at 90%??? I see your logs going above 155-160! I can't on a flat course! If I do a TT, I think I will never reach any LT.
Why this? What do you think? |

If you are training for a Half or IM, I think you need to work on building a stronger aerobic capacity on the bike and not work an 85% max HR zone, if I understand you correctly. We also discussed this in lenght here: http://www.beginnertriathlete.com/discussion/forums/thread-view.asp... |

We also discussed this in lenght here: That was a different topic. Focusing on long rides. I do not agree to focus all the trainings on zone 2 or zone 1 only. Like when you prepare a marathon, you do not train on zone 2 and 1 only: you go for IT, LT training as well (2k, 3k, 4k track and field intervals). Training on 85% does not mean I am going to push that effort on IM of HIM course: this training has a different goal and probably you know it better than me. Edited by Plissken74 2008-04-16 2:04 PM |

Extreme Veteran 370 Arnhem | Subject: RE: My cycling performances: what do you think? If you go bike outside on a flat road without too much wind can you get above 40 km/h at 136 bpm? I would say you are either a pro cyclist or the resistance on your trainer is not as high as it should be... |

I would say you are either a pro cyclist or the resistance on your trainer is not as high as it should be... To match the flat road, I checked my Polar on the 52-27 ratio at 90bpm and it is matching exactly the Sheldon Brown speed, cranck length 172.5. It is 49km/h. So I believe I am right, isn't it? |

No, I agree, check out that link I gave you. That was an entire thread on bike intensity training for long course racing. I personally train a low to mid Zone 3 on the bike even for long rides and think it can quickly build bike fitness. |

Extreme Veteran 498 Carpinteria, Ca. | Subject: RE: My cycling performances: what do you think? I am probably not even remotely on the level needed to comment, but I won't let that stop me. I end up training in a higher zone on the bike for a couple of reasons: 1. The bike for me is the place to push my fitness and HR harder than I can safely do on the run, because of the low impact nature of the bike. To stay healthy I have to hold back more than I like on the run because of lower extremity issues, but the bike affords me the opportunity to push into a higher zone and not injure myself. 2. I spent just a month on the bike just going as hard as I could for a half hour at a time and in just a month made enormous gains in my fitness. 3. The link and subsequent info as available on the link bryan posted for longer training goals. Pushing harder on the bike has allowed me to like the bike more than I thought. Going out for an aerobic swim or run is hard for me, very hard as the thing I like about training is pushing myself, hitting the bike harder allows me the opportunity to still "hit it hard" without missing too much from injury. I had a goal of being able to do better than 60miles in 3 hours in semi mountainous terrain before my HIM in July, knocked that out a few weeks ago with 63 or so miles iin three hours with 5k vertical ascent and same descent per my Garmin 305 and Motionbased software. Anything tween now and HIM is awesome. |

And, no, your trainer 'speeds' will still not likely match the roads even if you try to 'calibrate' it at a certain speed/cadence. Just do the work and the speed will be what it is. You need to start logging your workouts if you want any decent feedback though. |

Extreme Veteran 370 Arnhem | Subject: RE: My cycling performances: what do you think? Well I have no idea how your Polar or trainer work so I can't comment on how you checked things. But if I put your speed 42.3km/h into a cycling power calculator like this one: http://swiss2.whosting.ch/mdetting/sports/cycling.html(I have no idea how accurate this is, just to get a figure) and I use a weight of 64kg and 10kg for the cyclist and bike and no head wind it says you need to generate 424 Watts. That just seems a high figure to me (like that speed of 42.3km/h at 136 bpm HR) I think that is the kind of power an elite or pro cyclist can generate. That website has a graph showing the amount of power over time an elite athlete can produce. For a duration of 1/2 and hour it is 375 Watts Edited by Simondk 2008-04-16 2:38 PM |
