Edge vs TrainingPeaks 2026: Honest Comparison (UK Runners' Guide)

If you have started looking into structured running plans in the UK in 2026, you have probably come across both Edge and TrainingPeaks. On the surface they look like they do the same thing. They are running apps. They both help you train for races. They both sync with Garmin. Job done.

In practice they could hardly be more different. TrainingPeaks is the industry-standard analytics platform that elite and serious endurance athletes have been using for the better part of two decades. It is the tool of choice for around 90% of certified endurance coaches in the UK. It is deep, powerful, and built around the assumption that someone (a coach, or you) is going to write the plan and then use the platform to track it, analyse it and adjust it.

Edge is the opposite end of the spectrum. Edge is a UK-built adaptive plan app for the runner-lifter. You answer a few questions, Edge generates the plan, and the plan covers running, strength training and HIIT training in one place. There is no coach to bring in. There is no TSS to calculate. You just train.

This guide is going to be honest about both. We will give TrainingPeaks credit where it is due, because it deserves a lot of credit, and we will be clear about where Edge fits and where it does not. By the end you will know exactly which one you want, and probably why you want it. Let us start with the 30-second verdict.

The 30-second verdict

Pick Edge if: you want one app to build your plan for you, you are a beginner or intermediate runner targeting your first 10K, half marathon or marathon, you want strength training in the same plan, and you do not want to think about training load formulas or sit in a spreadsheet. Edge is built to take the planning off your plate.

Pick TrainingPeaks if: you already work with a coach (or want to), or you are an experienced self-coached athlete who knows what training stress score, chronic training load and intensity factor mean, and you want the deepest possible analytics on your endurance training. TrainingPeaks is the platform that serious endurance athletes have been using for a reason.

Use both if: you have a TrainingPeaks coach building your endurance plan but you also want strength sessions and HIIT mixed in. Some runners use TrainingPeaks for the run side and Edge for the lifting side. It works, but most people do not need this much.

Side-by-side feature comparison

The table below covers every meaningful difference. Be aware these apps are in different categories, so a "no" for one is often "by design" rather than a flaw.

Where TrainingPeaks wins

TrainingPeaks has been the platform of choice for serious endurance coaches for nearly twenty years. There are real, concrete reasons for that, and any honest comparison has to start by being clear about them. If any of these matter to your situation, Edge is not going to beat TrainingPeaks on these axes, and we are not going to pretend it does.

1. The industry standard for coached endurance athletes

If you have a coach, or you want one, the odds are extremely high they use TrainingPeaks. Around 90% of certified endurance coaches in the UK build plans inside TrainingPeaks. The platform was designed from day one for the coach-athlete relationship. Coaches build workouts in the planner, drop them into the athlete's calendar, see the completed sessions, leave comments, and adjust on the fly. There is nothing like it for that workflow. Edge does not try to do this. Edge does not work with an external coach you bring in. If coach collaboration is what you want, TrainingPeaks wins by a country mile.

2. Deeper analytics (CTL, ATL, TSB, training stress balance)

This is the other reason TrainingPeaks is the standard. It quantifies your training using metrics most other apps do not. Training Stress Score (TSS) puts a number on how hard each session was. Chronic Training Load (CTL) tracks your fitness over weeks and months. Acute Training Load (ATL) tracks fatigue. Training Stress Balance (TSB) tells you whether you are fresh or fatigued going into a race. Used properly, these metrics are genuinely useful. They are how serious endurance athletes track form and time their taper. Edge does not have this. Edge tracks progress in a more intuitive way, which is better for beginners but less precise for someone who actually understands the numbers.

3. Open workout structure (any coach can build any session)

TrainingPeaks workouts are open-format. A coach can build literally any interval session, with any combination of duration, pace, heart rate zones, power targets and recovery, and it will export as a structured workout to your Garmin watch. The watch will then beep you through every interval and target. This is incredibly powerful for prescribing specific work. Edge does not export structured workouts to Garmin in this format. Edge's runs are presented in the app with voice prompts, which works for most runners but is less flexible than the TrainingPeaks workout builder.

4. Power-based and heart-rate-based training

If you train by power (common for cyclists, increasingly common for runners with Stryd or running power on Garmin) or by precise heart rate zones, TrainingPeaks is built for this. You can prescribe intervals at specific power numbers or in specific HR zones, and the platform analyses your compliance afterwards. Edge does not do power-based training. Edge plans are pace-based or perceived-effort based, which is the right approach for most runners but not the right approach for someone serious about power-based work.

5. The free basic tier is genuinely useful

Most apps in this space have a free trial that ends. TrainingPeaks has a free basic tier that does not end. You can log workouts, see your basic data and use it as a permanent training journal without paying anything. The premium features (advanced analytics, multi-week planning, the full workout builder) are paywalled, but the basic tier alone has real utility. Edge has a 7-day trial and then it is a paid app. Both are reasonable choices for what they are, but if you want a permanent free training log, TrainingPeaks has it and Edge does not.

Where Edge wins

Now the other side. These are the five areas where Edge meaningfully beats TrainingPeaks, again not by a small margin. If any of these matter to you, the choice goes the other way. Most runners will find that one or two of these are decisive.

1. Edge generates the plan for you (TrainingPeaks does not)

This is the fundamental difference between the two apps. With Edge, you tell the app your goal (couch to 5K, first half marathon, first marathon, getting back into running after a break), and Edge generates an adaptive plan that covers running, strength and HIIT. With TrainingPeaks, the platform is empty until a coach fills it in, or until you buy a third-party plan from the TrainingPeaks marketplace and load it in yourself. TrainingPeaks is a container for plans. Edge is a plan. If you do not have a coach and do not want to spend hours researching which third-party plan to buy, Edge wins.

2. Hybrid programming (running plus strength plus HIIT)

Edge is one of the only major apps in the UK that builds running, strength training and HIIT training into one adaptive plan. Sports science is pretty clear at this point: two strength sessions a week reduces injury risk, improves running economy and makes you faster. With TrainingPeaks, a coach can prescribe strength, but most do not, and the platform has no built-in library of strength sessions or video demos. You would still need a second app or a separate strength plan. With Edge, strength and HIIT are just there, in your plan, alongside your runs.

3. Beginner-friendly (TrainingPeaks assumes a lot)

TrainingPeaks is a brilliant tool if you already know what you are looking at. If you do not, the interface is intimidating. You will see charts of TSS, CTL, ATL and TSB on day one and have no idea what they mean. There are tutorials, but the learning curve is real. Edge does not have this problem. You answer a handful of questions, Edge gives you a plan, and the app guides you session by session. If you are new to structured training, Edge will get you running consistently in a week. TrainingPeaks might still have you watching explainer videos.

4. Better value for what most runners need

TrainingPeaks Premium is roughly $14.99 a month, which works out around £12. That is cheaper than Edge at £19.99 a month. But the comparison is not apples to apples. TrainingPeaks Premium gives you the analytics platform. You still need to either pay a coach (typically £100 to £300 a month on top) or buy a third-party plan to actually have a plan to follow. Edge at £19.99 is the plan, the strength sessions, the HIIT sessions, the voice prompts and access to Edge AI all included. For a runner without a coach, Edge gives you more for less.

5. UK-built for UK runners

TrainingPeaks is a US platform out of Boulder, Colorado. It is genuinely global, and that is part of its strength. But the content, the example athletes, the community and the cultural references all skew American. Edge is UK-built. Distances are in kilometres or miles by your choice. The community is UK-based. The 17,000+ members are mostly running UK parkruns and UK race calendars. For a UK runner, that local-first feel is worth something, even if it is hard to quantify.

Edge or TrainingPeaks? Decision tool

Answer five quick questions. We will tell you which app fits your situation, or whether you should run both.

Pricing breakdown

The headline numbers tell only part of the story. Here is the honest cost of using either app for what most runners actually want.

The realistic total cost of TrainingPeaks Premium plus a coach is in the region of £120 to £320 a month. The realistic total cost of TrainingPeaks Premium plus a pre-built marathon plan is around £52 in the first month then £12 a month. Edge is a flat £19.99 a month for everything.

The right comparison is not always price-against-price. If you need a coach, TrainingPeaks plus that coach is still the right answer at any cost. If you do not need a coach, Edge gives you more value at less than the cost of TrainingPeaks Premium plus a plan.

Who is each app for?

Edge is for: the beginner to intermediate runner-lifter

If you are running your first 10K, half marathon or marathon, or you are getting back into running after a layoff, Edge is built for you. The plan generation removes the hardest part of training (knowing what to do this week). The hybrid programming means you are not just running, you are building a body that runs well. The voice prompts and coach video demos make it feel like you have a trainer in your pocket. Most of Edge's 17,000+ UK members fit this profile.

Edge is also for: the runner who knows they should be lifting

Plenty of intermediate and experienced runners know they should be doing strength work but do not, because adding a second app or a separate gym programme is friction. Edge solves that. The general strength and mobility sessions are programmed to complement your runs. It is not bodybuilding-specialist programming, but for a runner it is exactly the right dose of strength work.

TrainingPeaks is for: the coached athlete

If you are paying a running coach (or you are about to), TrainingPeaks is almost certainly the platform they will use. This is the deepest reason to choose TrainingPeaks. The coach builds your plan inside it, you complete sessions, the data flows back, the coach adjusts. This workflow has been refined over twenty years and it is genuinely best in class. Edge does not try to replace this and you should not try to use Edge in this way.

TrainingPeaks is also for: the experienced self-coached athlete

If you have been running seriously for years, you know what training stress means, you read training science papers for fun, and you want to build and adjust your own plan with the best analytics available, TrainingPeaks is the right tool. You will use the workout builder, you will look at your CTL chart every week, you will time your taper using TSB. This is what TrainingPeaks was built for and it is brilliant at it. If this is not you, the depth will be wasted.

Honest caveats (both sides)

No honest comparison is complete without saying clearly where each app falls short. Here are the things we will not pretend are not real.

Edge caveats

Edge is not a deep analytics platform. There is no TSS, no CTL chart, no TSB. Progress tracking is intuitive, not metric-heavy. If you want the numbers, Edge is not it. Edge does not integrate with a human coach you bring from outside. You cannot give your coach a TrainingPeaks-style athlete view. Edge does not export structured workouts to your Garmin watch in the format TrainingPeaks does. The plan is followed in-app with voice prompts, not on the watch face beep by beep. Edge does not do power-based training. Edge strength sessions are general programming, not powerlifting or hypertrophy specialist work. The Edge AI is helpful for 30-second questions and there is the option to speak to coaches, but it is not a substitute for a paid human coach building a periodised plan.

TrainingPeaks caveats

TrainingPeaks does not build the plan. The platform is brilliant, but until a coach or you fills it in, it is empty. The learning curve is steep if you have not used analytics-heavy tools before. The interface is dense and assumes prior knowledge. There is no strength programming and no HIIT programming. You need a separate solution for those. There is no voice coaching during runs. The workout shows up on your watch but you are on your own for the audio. The community is global and US-skewed, which can feel less local than UK-built apps. And the real cost of getting full value out of TrainingPeaks (premium plus a coach or a third-party plan) is higher than the headline $14.99 a month suggests.
