Marco: For more than a year, I’m doing a sports routine similar to yours in terms of cycling and running; I will run the Chicago Marathon in a few weeks (October 8) and will be so excited to share my data both in HRV and Trainning Peaks with you.

Let me know if you are interested. My email is alejo_alzate@hotmail.com.

Thanks Marco. Very interesting. Are you living in Amsterdam now?

I am interested to know how you can discover where your strengths and weaknesses lie in fitness. How do I know if my vo2 max is good? How do I know if my muscle endurance is good or bad? Are there some measurements I can compare beyond subjective muscle soreness scores?

I have to be extremely careful with training these days due to life stress, so it would be interesting to tailor it to my own profile. Any info is welcome!

thanks Cecily, often the most informative for me is simply training and racing times over the years, in relation to others. For example, if I have a certain 5 or 10 km time, and I train high volume, but still struggle to race a comparable marathon time, the issue is in economy and durability. VO2max can also be tested in the lab, even though here what matters the most is the relationship between VO2max and economy (there is possibly a negative correlation between the two at the population level).

We know that high heart rate on the bike and run are entirely different. They are two different physiological disciplines.

You can't maintain the same running fitness while cycling. Your eg is representative of that. Your heart rate in the 180’s was more than your MHR for the bike you had little or no power to maintain the same output you would on your bike.

A rowers Max heart @ 210 is entirely different than a runners max heart @ 210 and the same goes for a cyclist who's max heart rate is 210 / your VO2 max in all 3 disciplines would be different an FTP for cycling and rowing would be much more representative of your max load and commensurate w/ your max effort from a runners, swimmers, and winter biathletes.

All athletes who use a bike, rower for sitting and power would be entirely different than an athletes who depend on their entire body for max out-put. Specifically endurance and sprint athletes.

Marco for eg you could've added over unders / sweet spots in your cycling training during your injury and downtime from running. OU/ and SS would increase your power and teach your legs to buffer your LA (lactic acid) this would be entirely different than from a runner producing LA w/ volume build or incorporating fartlek training to increase speed. Cycling power and rowing power offer greater forms of data bc you can you use FTP / watts for out-put and heart rate training zones. They are now incorporating that kind of data for swimmers Xcountry skiers

Cycling and rowing are much more technical.

A cyclist max heart rate 194 and max power @ 1100 watts for 20-40 seconds is entirely different than a cyclist max heart rate @ 166 max power 289watts for 4hrs.

Avg heart rate for 30-60 mins for cycling / running would be entirely different if both had high heart rates @ 174

Most athletes. Cannot attain the same heart rates in one discipline to another disciplines due to neurological, physiological, barriers.

no doubt! but we can still maintain large part of our fitness by cross-training, that was the point of the blog here, not that they are replaceable (of course they are not).
