Drew's Intervals with HR Field


A field that allows you to configure a complex interval session with heart rate, distance or duration through GE or the GC appThe field is configured using a programming language I have created to describe the interval training. There is a cross hair which shows how far through the phase and where in the zone you are. It is fairly ambitious in view of the size constraints of a field and I feel like I have squeezed a quart into a pint pot. The language is simple and accessed through configuration of the field in the app or online. If we have selected duration (I can also select distance) in minutes then a phase is described by say [5,1] which is five minutes in zone one. Intervals are linked together with a plus sign so [5,1]+[5,2] is a warm up starting in zone 1 for five minutes then zone 2 for five minutes. I can use parentheses and a multiple such as 4*( [5,5]+[2,2]) which is four lots of the linked phases. It is possible to nest these and produce highly complex workouts such as [5,1]+[5,2]+2*(3*([5,4]+[2,2])+[5,1])+[10,1].


All (but virtually identical to my app for intervals with power)

Update to my snarky and much too negative review from before. With great help from the developer, I think this data field will work well for me. So much better than taping a paper workout script on the handlebars :) I understand better now the limits of doing this kind of magic within the tiny memory confines of many Garmin devices. Well done with this field!! Beer funds coming your way, Drew!

I was so excited to see this data field. However, it turns out to be very kludgy and inoperative on my Vivoactive HR. It works great one day, and then the next day only the IQ logo with exclamation point shows, or the two arrows with lightning bolt. It’s great to have this free field, but it’s so much work. I’ll keep an eye out for an update. Perhaps my watch is failing. Best regards.

Hi Casey. I no longer provide updates for this field ( I am a single handed developer and this activity generates no income ) I suspect you are running out of memory as the memory allocation of a data field (as opposed to a frequently confounded CIQ app) is pretty limited. The Drew's Intervals app should however run on your device. (BTW the native HR measurement on the old VA HR is not really accurate enough for interval training). A 2 star review - thanks!

Eine sehr gut app. Es wäre schön, wenn man die Zonen umbenennen könnte, da die Zonen nicht zu meinen bei Garmin connect definierten Zonen passen. Wenn das möglich ist, gebe ich 5 Sterne. A very good app. It would be nice, if I could change the name of the zones, because the zones now arn't similar to the zones I am using in garmin connect. If that is üpossible I will give 5 stars. mfg Jörg

Thanks Joerg. That would be pretty easy to do. My big problem is having time to develop as I am a doc but I will eventually get round to it (-:

Только хотел спросить, когда зпилят интервальный тренинг по пульсу, а она уже вышла. Вопрос, если я установил 2 поля они будут синхронно работать, hr+power?

Thanks Алексей Good question. I think you are limited to 2 CIQ data fields in an activity but as long as you use them for this I see no reason why it would not work. They will start simultaneously. You would have to ensure both workouts had the same time intervals or it would drive you mad (like driving with two sat navs with different routes!) All the best Drew
