Bike Course Comparison: Ironman Lake Placid vs Coeur d’Alene

IMLP vs IMCdA BikeSeveral people have asked me how Ironman Coeur d’Alene compares to Ironman Lake Placid, namely the bike courses. So, I decided to attempt to answer that question with a bit of a comparison of the data that I accumulated from the last two races. It was fairly difficult to find any one tool that conclusively compared the two courses, so I used a few different methods. It is a bit off-the-cuff, but it might help to give some people a little idea of how similar or different these coursed really are.

First off, I tried using Garmin Connect. While it is pretty easy to select two rides and click compare in GC, having IMCdA recorded as a “Multisport Activity” from my Garmin 920xt proved more difficult to compare since IMLP 2014 was recorded as just a single ride. Then I had to export the IMCdA Ride as a TCX file from the MultiSport activity and re-import it again by itself. When I did that, it didn’t calculate my Normalized Power watts at all and my average watts were off by about 3 watts. I then filled them in manually. So I finally got them in a table format which is below.

So, these courses above look very similar. The only major differences was my power output for Coeur d’Alene was about 20 watts less on average and normalized power. Note that I used the same Stages Power Meter for both races. The corrected elevations here show only 400 more feet of climbing at Lake Placid and about 500 more feet of loss as well.

Next I jumped over to Strava where I have the Stravistix extension which provides some more information on the grade of the courses. Thanks to the Stravistix Google Chrome Extension for Strava from Thomas Champagne for the statistics below…

Here again, the courses are very close. The only thing that really stood out to me was that IMCdA has a little more flats and IMLP has a little more downhill.

Equalizing Course Profiles at 0 Elevation

I also was able to import the original Garmin FIT files into Golden Cheetah, which allowed me to the export the raw data points from each ride/course into a spreadsheet. I then imported those rides into my favorite analysis tool, QlikView.

I equalized the starting elevations for each course to zero for each race profile. Next, I adjusted the rest of the points elevations’ by the difference from that starting elevation to zero. Plotting this way then moves the course profiles on top of one another(below) as if they started at exactly the same elevation. This gives us a interesting perspective of the courses that I would not have seen looking at the numbers above. While the numbers look the same the profiles are very different.

The Coeur d’Alene course is much more up-and-down in the range of 0-500′ climbing. Lake Placids’ long downhill section into Keene provides you with a nice long and speedy descent, but then you pay for that later with the very a very long, gradual climb from Jay all the way back to Lake Placid. This climb continues on into your second loop at LP too after heading through town. So if you like a constant gradual climbing then Lake Placid is more your style, whereas CdA is more for the folks who like big rollers.

The one thing I didn’t take into account here was the wind. For Ironman Coeur d’Alene 2015, the wind was coming out of the NNE mostly at around 7 MPH. This provided a nice tailwind from mostly the first turnaround at Heggins Point all the way out to the second turnaround. Coming back to town thought was obviously a headwind. Not a bad one, but I could definitely feel it. Lake Placid in 2014 was a little higher at around 8+ MPH out of the South. It always seems to just whip right up through the Wilmington Notch as you are grinding your way back to Lake Placid. 2014 also had a the nice edition of nasty thunderstorm on the first half of the first loop too.

EFD -Effective Flat Distance Overall

For one last comparison, I had stumbled upon the Flacyclist.com site by Tom Jordan. Tom has a calculator tool he put together that figures our what the Effective Flat Distance(EFD or EDO) of a ride is. This is basically how long the ride would be if you took into account the climbs and descents and just flatten everything out. It seems pretty complicated, but probably a more accurate way to equalize different courses for comparison.

I downloaded Toms’ spreadsheet version of the calculator and filled in the data. Getting some of the required fields tooks some data wrangling. I used the ride extract from Golden Cheetah and then did some Excel magic to figure out the climbing(> 1%)/descending(< -1%) distances. I had also downloaded hisorical weather info from Weather Underground site. I used some default values for area of rider and things like that. I set the wind direction at 45 since both courses were basically out-and-backs so there was a combination of headwind and tailwind. You can view the calculations here…

Looking at the two course calculations above, you can see the (EDO or EFD)Effective Overall Distance for each ride is in the 2nd to last row of each image above. The first distance value is taking wind into consideration the other is not. Based on the no wind calculations here, the IMLP was equal to about 121 miles in EFD but the IMCdA course was just a couple miles more at 123 giving it a very slight edge in difficulty. But not much

Taking the wind into consideration, IMLP 2014 averaged about a mile or so more per hour(8.24mph) over the time on the bike course than IMCdA 2015(7.4mph). With an equivalent amount of head vs tailwind, this effectively evens both the courses out at about 142 miles and some change.

This comparison also seems to point to both courses being very comparable in difficulty. The only difference being what type of ride do you prefer? Do you like to maintain a steady uphill climb over a long distance or do you prefer more shorter ups-and-downs?

Ironman Coeur d’Alene Bike

Personally I liked both courses in their own way I guess. I really feel like I could have PR’d the Coeur d’Alene course under normal temperatures this year. Once that heat kicked in, the wheels just fell off. Despite that I was still able to come in only 5 minutes later than Lake Placid the following year. I was under 3 hours for the first 56 miles while the temperatures were still reasonable.

I hope that was somewhat helpful to anyone considering either of those races. They are now moving the full Ironman in Coeur d’Alene to August next year, so 90-100 degree temperatures may be the norm for that race now. Some locals told me that that weather is more typical at that time of year there. That pretty much takes that off my list of races to try again! Hopefully next year I can compare the Ironman Mont-Tremblant course to these two courses.

Thanks!

 

A Really Off, Off-Season 2014

Well, I am back. This off-season has been pretty uneventful ever since I completed Timberman 70.3 back in August. We did take a trip to Italy back in September which I just finished posting yesterday. I have continued to train and I did complete the 180 mile City-to-Shore ride, but I have had more achievments on Untappd than on Strava this fall. With those acheivments comes a snug waistline and around 15 lbs extra weight above my racing weight I need to shed. The lowest point was the week of Thanksgiving where I literally did absolutely no training that week. Unheard of! Apparently I needed this little break and I am trying to listen to my body a bit. Keeping up that motivation for Ironman training after 3 years is not always an easy task. 2013-07-27-16.31.42.jpg

But, I am back in the swing again and I am getting geared up for Ironman Coeur d’Alene in June and the St. Luke’s Half Marathon in May. Other than that I have nothing else planned but hoping to do so late season local races. I was tossing around Ironman Maryland as well as Steelman. Still thinking that over.

The last couple weeks I have been back at it pretty steady and I am feeling pretty well. I seem to have carried over my endurance because I am go out run a half-marathon, swim an easy 3000 meters, or ride my bike for 3 hours  without issue. Given that I trying to focus more on developing some speed and power for this season. I still have a goal completing an Ironman in under 12 hours which I carried over from last season.

In the pool, I have started using a Finis Tempo Trainer.  I have a very low stroke rate and am pretty much a glider. With that my lack of ability to do flip turns my typical stroke rate shows up at around 56-58 spm(both arms) on my Garmin 910xt. That translates to around 2:00/100m which is not great. I typically swim around 1:46-7/100y in open water which basically washes out the need to turn. So my plan is to try to gradually increase my turnover rate in the pool to increase my pace. I know that when I get my strokes/min into the high 60’s or low 70’s I can get down to about 1:50/100m which equates to about a 1:40/100y. If I can work on maintaing that pace for IM swim it would be cut down to about 1:11 or so. Actually I would be happy to get to a 1:15, which is 2 min improvement over the last 2 years.

On the bike, I am back using TrainerRoad again through the Winter months. This software helped me make huge gains in the bike last year. I went from a 223 FTP to a 253 which is 13% increase. It really showed on the bike too, I cut about 15 minutes off my Lake Placid bike leg and I had a great ride at Timberman finishing well under 3 hours. I am doing the same training plan I used last off-season and am looking for 10% gain edging to maybe 275-280 FTP.

I need to generate some more speed on the run for sure, especially after a long bike. My goal would be to finish the IM Marathon portion in around 4:10, which equates to a 9:30/mi pace. So, this is my floor pace for all my longer(LSD) runs this season. Other than warm-ups, I am going to make this the slowest I can go or I will have to cut distance in order to maintain it. I know I can run the distances at 10+ pace, so now it is time to step back and take it up a notch. I also want to incorporate some longer brick runs off the bike. I seemed to suffer more after the first 6 miles during IM and I need to work that out. During the week I will continue the tempo and interval runs as I did before.

Getting back to racing weight will also be critical for all this to happen. I feel I have my race nutrition plan pretty solidified, which is anchored by my good old Amrita Bars, but my off-season nutrition needs some work. A few too many pizzas and IPA’s this year, so I will be cutting that all out come January 1st.

Here are a couple good articles that I recently read on off or base season training that provide a little different twist on the traditional approaches…

If any of you are on the Zwift beta program and you are looking to ride with someone let me know too.

So I hope to get some more posts going here very soon. I have a couple training excursions and some product comparisons and reviews coming up too which should be interesting. So if you have stuck around, I hope you will continue to read on. Thanks for reading.
