First time runner - how best to use Epic for Couch to 5K?

I would just follow the daily suggestions.

To get a VO2max estimate and training status you need to do few runs first...do it at your own pace but they have some requirements https://www8.garmin.com/manuals/webhelp/GUID-E5C62F3F-DCE3-4197-8CA5-E419B2A55D12/EN-US/GUID-015C6746-435D-48E0-8ED8-CA2C81684E38.html 

1. Wait until firmware 9.33 has been pushed to your watch.

2. Create your personal 5k race in the Garmin calendar, with a target time you would like, and a 5k course you want to run. Pick a suitable date in the future.

3. Set the race as your Primary Race

4. Follow the Daily Suggested workouts, which will dynamically adopt and guide you towards your goal, and give you updated race time predictions.

5. Run the 5k race.

I used the garmin coach to successfully go couch to 5k having struggled with different couch25k programs/apps. The coach is guided, asks a few simple questions and sets it all up including a schedule. Saves building dedicated plans if you are unsure where to start. On the garmin connect app go to training>training plans. 

Thank you all for your replies.

I'll get the new firmware and try the Garmin coach. Does this guide you via earbuds e.g. tell you to walk for so long, jog, run, walk again etc?

One of the coaches uses a walk-run principle. Haven't tried it, but I assume it will tell you when to walk and when to run. The downside of the Garmin coaches is that they are pace based, not heart rate based. The new adoptive Training Plan feature you get in firmware 9.33 supports heart rate based training plans.

Use the Garmin Coach functionality of Garmin Connect. It’s self explaining. 

Coach Jeff doesn’t tell you „walk now for x, than run for y“ but teaches how to select when to do what. 

It took me a bit of time to figure it out, but it uses beeps and on-screen indications to tell you what to do. But the program is pretty nicely laid out. I'm following Coach Jeff Galloway's program. The results show up in the Garmin Connect app on the phone

Use the Garmin Coach Training plans and choose Jeff Galloway as the coach. As a first time runner, choose the goal to finish the race, not a time-based goal. Of the three coaches, Coach Jeff Galloway gives you the easiest start off point.

Use the earbuds connected to the watch directly. This way, you will have the count downs, the goals of the starting lap, the feedback against etc. that are not available when you go through your phone.

Train on flat courses. Using pace instead of HR is actually much better, if you train on flat courses. If run in hills, you will have to use a 3rd-party training plan with running power goals on a 3-rd party training platform like Trainingpeaks. More complicated, more costs... Using HR for a 5k-training, which includes many interval workouts, is not optimal because HR lags effort. So you will have a tendency to run harder to get the HR to the target training zone and will overshoot.

Thank you
