Aside from monitoring your MPH during the Bike run, I'm curious to know what secondary mode on your bike computer display is important to you. Is it your Cadence, Elapsed Time, HRM or Etc? For me, I monitor my cadence but should I be looking at the Elapsed Time to know where I stand being above or below my PR or is there a standard secondary mode that most Triathletes use and why? Thanks!
I like to have my cadence displayed on my watch but I also keep an eye on my heart rate, I don't want to burn out before the run. I find keeping my heart between zone 3 & 4 works well for me on race day (generally kept in zone 3) obviously as you climb and pass your heart rate increases but having the watch right there to beep and remind me to keep my heart rate in check insures I have enough in the tank for a solid run time too. Good luck.
Good topic! I usually have cadence, then on my watch running time. I've also used ave mph.
I've had issues in the past: went over a bumpy section & the display freaked out. I forgot to take it off my bike once when the bike was on my car bike rack for a long drive... lost that one.
And sometimes the little cadence magnet gets bumped.
But overall I love #'s, so I love the bike computer.

I have 3 displays, so I usually (almost exclusively) have cadence and avg speed. Then my watch tells me HR, time, climbing stats, and anything else you could ever want. I like to watch cadence because it keeps me honest. I have a tendency to throw it into a higher gear and pound instead of keeping cadence up. In triathlons, it seems like a good idea (IronMakeover can back me up here?) to keep cadence up on the bike so that your legs aren't dead for the run, so keeping cadence in my face the whole time helps. That said, I've lost my computer in both tris I've done - the first because the battery died 3 minutes into the bike, and the second because the strap holding the magnet to the fork broke about 4 miles in. Yes, I'm that lucky.
Thanks for all the great comments. One thing I have learned is get more gizmos to keep track of how my body is performing (a.k.a HRM). I have a watch but only to keep track of the elapsed time but I haven't trained myself enough to look at it because I'm concentrating on trying to breath and do that other stuff - like swim, bike and run. I'm not the most coordinated individual here.
I display my cadence and try to pedal between the high 80's to low 90's. I too have a tendency to want to push higher gears and by the time I realize what I'm doing I end up blowing up on the run. I need to learn more about the use of the Heart Rate Monitor and the Zones. I like the idea where a device like a watch can remind you to back down before you blow a gasket!
Just my $.02, but get a Garmin 305. There are a lot of others that people may suggest - and for good reason - but for the money I don't think there's anything comparable out there.
I usually pay more attention to cadence and yes ofcourse you should be looking at your elapsed time. I think mostly triathletes use the same practice.
Does anyone have any input on wireless verses not as far as bike computer accuracy? Just got my new tribike and wanna avoid zip tying wires to it.. Also, does anybody use their iphone as a gps, if so, how is it working for you? Thanks.
I have both wired and wireless Double Cateye computers. Riding side-by-side with my wife, matching speed and cadence - both are very, very close to calling it even. Sorry, can't help you with the iphone - but that sounds really interesting.
I have a wireless Cat Eye and so far it has been NOTHNG but trouble. It has been back to the shop four times and never has worked right. I am going to exchange it for a wired one this week because I am tired of it not working (yesterday out on a flat stretch it had me going 17 mph--11mph--5mph--21mph--all in the same 3 seconds of time). It may be that I just bought a lemon of a wireless but it just won't work right, even after being "fixed" multiple times.
I heard the bike shop guy say that the wireless ones are a problem at times, but I also know a lot of people that use them with no issues whatsover. I'm not one of them though. Just a heads up for ya.
I agree about the garmin 305. I have it with the quick release system. I also added the speed and cadence for the bike. When on the bike I keep 4 displays up, cadence, ave speed, time duration, and distance.
Dr Miles I like your humor! "...because yes I'm that lucky!" Thanks for the smile!!!
At the USAT clinic CTS coach Fiona Lockhart referenced a study talking about cadence & its impact on run performance:
- 60 minute bike, 3 groups, one group biked at preferred cadence, one at 15% above, one at 15% below.
The triathletes who pedaled faster or at prefered cadence were faster in the beginning of the run, but NOT overall.
From a different part of Fiona's lecture (excellent speaker/coach):
- pedalig at a high cadence is very much a learnable skill
- vast # pedal 90-100
- below 85 if not on a climb will cause muscle fatigue over time, if you wear out legs you won't get them back on a ride.
Also Joe Friel has this good post mentioning 2 studies on cadence:
He writes "Take your pick: pedal at a low cadence before entering T2 or pedal at a high cadence before T2. One of them will improve your run performance. Which one? I wish I could say."
Best to you all,

I use a G305 and display four numbers: speed, average speed, cadence, and heart rate.
Elapsed time is on my watch, but isn't very important if you just translate your PR time to an average speed, you basically know how fast your going based on being over/under this target.
