Hello intervals forum,
Love this software and have used the fitness tab to aid in proper fitness peak for multiple cycling events.
My question comes when switching my primary activity to running and regardless of my sessions, my form trending up. I did come off a fairly heavy cycling block and then switch directly into running. I cycle with power and run with HR (Apple Watch - not amazing at recording) synced in via Strava.
I’ve added max HR and adjusted my zones in intervals profile to match my training zones for running. I’m peaking for a marathon right now and mileage is high as ever, albeit intensity is quite low - and my form is still shooting upwards in transitional.
Are my runs not heavy enough or was my previous cycling training just that heavy that the runs truly are less?
I feel I’m missing something with the software.
Thanks in advance.
It’s more likely that your HR zones aren’t set correctly for your physiology and that the resulting HR load is an under-estimation of what is really happening.
Mixing up loads from HR and Power isn’t the best idea, unless you already have a lot of data with both power and HR. With that data, Intervals creates a model that judges HR load far better for activities without power.
You sound like you already have quite a bit of data from longer activities so you can verify somewhat because 1hr cycling load at 70% intensity results in a 49 TSS load.
1hr running at marathon race pace, should result in a pretty similar load.
Thank you - I’ll have a look at the zones again as I assumed that was the culprit. If the example you’re provided holds true - I’m majorly under reporting my loads from running.
My cycling data is just power or just HR so the data is a bit incomplete to go back on long term.
