What does Edge do?
Edge's home page says it builds one adaptive plan for your running, strength and HIIT. These are the parts its own pages describe that matter most when you choose a coaching app, each drawn from our register of rival facts and linked to the page it came from, read on 16 October 2026.
- A person reviews your plan or replies. A coach checks every plan before it is released, and a real person reads every message.
- Chat with a coach (AI or person). Edge AI changes a session's length, exercises or intensity; its coaching team takes injury, taper and technique.
- Shows how to do each exercise. Video demos for every exercise.
Two things stand out. A person is in the loop: a coach looks over the plan before you get it, and a message to the coaching team is read by someone. And the work is split between software and people: Edge AI takes the small daily changes, and the coaching team takes the bigger questions. That is a sensible split, and a real difference from Smash Coach, which has no human coaches. Flexi Swap, for the week that goes wrong, comes up below, where Smash Coach works differently.
How does Edge treat a class or a sport?
Classes first. Edge's pages say Edge builds your running plan around your gym, your classes and your schedule; a class whiteboard can also be scanned in as a workout. If a weekly class shapes your week, that is in Edge's favour.
A sport you play is a different case. On 16 October 2026 we read every page listed in Edge's site and help-centre sitemaps, the 916 of 920 that still load, and searched them for sports by name. Its guide for cyclists who run says a real coach can factor your riding into the week and balance the rest of your training around it, and its pages on swimming for runners and on the Ironman World Championship in Kona say you can message a coach about fitting your swims, and your rides, around the plan. Planning a week around a match, such as a Saturday football match or a padel league night, is not described on those pages.
That is a statement about Edge's pages on that date, not a finding about the app. We do not know what its coaching team would do with such a request, and its pages do not say either way. If a match sets your week, ask them before you subscribe.
A plan that cannot see Saturday's match can put hard legs on Friday. Each session can be well written and the week still be wrong, because the plan was never told what else is in it.
That is the whole case for telling a training app about your sport, and it is a planning point, not a fitness one: does the app know the match is there?
Where is Edge ahead?
On these, Edge's pages describe more than Smash Coach offers. Each comes with the Smash Coach side next to it.
- A person checks your plan and answers you. Smash Coach has no human coaches: its coach is AI. A person looks at a session or change when it fails the automatic safety check (it shows UNDER REVIEW), and feedback you send from the You tab reaches a person, not a queue.
- Video demos. Edge's home page lists video demos for every exercise. Smash Coach shows each exercise as a clean illustration on a plain background, with nothing extra, and the team is exploring video and moving images. If you learn a movement by watching a person do it, that counts for Edge.
- The app stores. iOS and Android apps, and the web. Smash Coach installs from the website to your home screen and is not in the app stores.
- More watches. Edge's help centre lists Garmin and COROS sync, and an Apple Watch app. The Watches row in the table below sets it beside Smash Coach.
- More races. Add a race, such as a 10K, a marathon or HYROX, and the plan builds to it and tapers. In Smash Coach, HYROX is the race you can pick today; ATHX, DEKA, GYMRACE and running races from 5K to the marathon are coming soon.
What does Smash Coach do differently?
Smash Coach begins with what is already in your week. You tell it the sports and classes you do, and with Pro or during your trial your coach plans the rest of your week around them, not on top of them.
- Add a sport. Go to You, then SPORTS STACK, then + ADD. A sport is supported from the outside: with Pro or during your trial, your coach plans around it. See Add a sport or a class.
- Add a class. Pick it from GROUP CLASSES. A class counts as training you have done, so with Pro or during your trial your coach adjusts what it gives you instead of adding on top. It starts on Fixed days, because a timetable decides when it happens. With Pro or during your trial, its warm-up toggle offers a short activation routine to do before the class.
- WHY THIS DESIGN. On a session your coach wrote with Pro or during your trial, tap WHY THIS DESIGN on the gold card to open the reasoning behind it, and the assumption it made if it had to make one. See Read a workout.
- A coach chat that knows your week. With Pro or during your trial, ask in your own words; a change arrives on a card, and nothing reaches your plan until you tap Confirm. See What you can ask and Apply a change.
- Swap an exercise mid-session. When the kit is busy, DO IT LATER moves that exercise to the end of the working section, before any cool-down; when it is missing, your coach offers up to three swaps that train the same thing, with Pro or during your trial. See Swap an exercise.
Moving a session
Here the two apps describe different things. Edge's home page says: Move a session with Flexi Swap and the rest of your week rebalances around it. In Smash Coach, a session you move stays where you put it, and nothing else in the week changes, because, in the help centre's words, one move should not cost you a reshuffled week. If you do want the week rebalanced after a move, ask your coach in chat, with Pro or during your trial.
Neither is wrong. If you want the rest of the week to rebalance when you move a session, Edge's home page describes that. If you move sessions to fit a fixture and want everything else to stay put, Smash Coach does that.
Edge or Runna?
If you are also weighing Runna, these four rows from each app's own pages separate them most clearly for someone who plays a sport. Smash Coach is in the table too.
Read the first row first: neither Edge's pages nor Runna's, read on the same date, describe planning a week around a match. After that, the races row matters most if your goal is a running race, and the person and demo rows if you lift as much as you run.
In our view, Runna suits a runner whose goal is a running race from 5K to 50 km, who wants plans designed by running coaches, strength sessions alongside and wide watch support. Our full comparison is at Runna or Smash Coach.
How do they compare?
Every Edge fact on this page comes from Edge's own pages, each one linked, read on 16 October 2026. Before writing the sports row, we read every page listed in Edge's two sitemaps and searched them for sports by name.
UK rules on comparative advertising ask for an objective comparison of verifiable features that does not denigrate a competitor, which is why each rival cell links to the page it came from. We recheck the table every quarter.
Which should you choose?
Choose on what sets your week. In our view, Edge suits someone balancing running, strength and HIIT who wants a coach to check the plan and answer messages, with video demos and an app-store install.
Our view is that Smash Coach is the right choice for an athlete who does more than one sport, because it plans one week around every sport and class you do, with Pro or during your trial, which also brings a coach you can talk to and a plan that is rewritten when something real changes. It shows each exercise as a clear illustration too.
What Smash Coach lacks, plainly: no human coaches, Garmin is its only watch, HYROX is the race it plans for today (other hybrid and running races are coming soon), it installs from the website rather than the app stores, and it shows illustrations, not videos yet.
For more apps side by side, see hybrid training apps compared. If the person in Edge's loop is what draws you, our page on an AI coach or a personal trainer sets out what each one sees. Every comparison is on the Compare page.
