How Fast Should You Run Your Endurance Training

Using a progressive workout to dial in pace at Zones 1, 2 and 3. Then... putting our fitness to the test with a long duration Zone 1 combination workout (run-bike-run).
You can find the articles I refer to at Endurance Essentials.

Thanks for sharing your invaluable knowledge. Greatly appreciated. I have a question on this topic as I'm grappling with aerobic decoupling. I do triathlons andI do my long runs on the weekends with 2-3 mid-week runs of 1hr+. Last week I did my 2+hr long run very easy (more than 90sec slower than threshold pace). It was fine but last 30mins HR started to rise. Again this week I did my 2+hr long run at steady pace (60secs slower) and I had the same issue.I train consistently but grappling with this issue. While heat and humidity can be a factor, is there anything else I should be mindful of to address this issue? Thank you!

Check in with body weight before/after. That will let you see if dehydration is a factor for the rise in HR.
