Thanks for all these new features!

David, Intervals.icu has become essential for many of us, coaches and triathletes alike. To secure the platform’s future and accelerate further development, have you considered launching a crowdfunding campaign? We could either go for a traditional campaign with premium perks for supporters or even allow community members to symbolically become shareholders or financial partners. It could create tremendous momentum and even greater community engagement around Intervals.icu. I’m sure many of us would be excited to support you in this direction! What are your thoughts?

Thanks for the support. Enough people are supporting the platform for me to work on it full time so its future is secure. I am going to continue adding new premium features to encourage people to subscribe. My wife (also a developer) will also be working on Intervals.icu from June.

There is a big Google doc with all the accounts, server details and so on. Should something happen to me a friend of mine (who runs software company) will look after the project.

These are all great additions to an already great platform. I am having trouble trying to copy planned calendar events from one athlete to another. When I copy an event, it keeps pasting the wrong event into the second calendar. It keeps pasting the same event over and over instead of the most recently copied event.

12

Hmm I just tested that again copy and pasting some events from my calandar to another and it worked fine.

Are there any errors on the Javascript console when you copy? Right click on page, choose inspect element and go to the “Console” tab.

13

I got it to work. I was trying to copy and paste entries between two open browser tabs. If I do it in one tab and toggle back and forth between different athletes it works perfectly.

14

There is an epileptic machine And why is there no electric treadmill in the gym as equipment and is there a plan to add treadmill training?

15

Thank you for all that you do! I am especially excited about the new power curve options. Only other thing that I can think of for me personally would be to have an option in the settings to change the start of the week to Sunday, as that’s what I use for everything else and it’s really confusing. Really appreciate the update though!
