If you're reading this, you probably love being on the track or in the park, but spend more time than you'd like staring at a screen. Excel is an old friend to every running coach: it's free, it's flexible, and it got us out of trouble early on. But it has a very low ceiling.
When you have 5 clients, you can remember their paces and which race they have next month. Once you go past 20, Excel turns into a maze. A single typo in a cell can mean an athlete does a workout that's not theirs, or worse, gets injured. If you want your business to grow, you have to stop being a spreadsheet clerk and go back to being a coach.
The problem with "fake" manual personalization
Many coaches believe that for a plan to be personalized they have to write every session from scratch every week. That's not personalization, it's inefficiency. Real quality personalization is based on adjusting key variables (volume, intensity, density) on top of a solid methodology you've already proven works.
The problem with Excel is that it doesn't scale. Copying and pasting cells for 30 different people eats up hours you could be spending on bringing in new clients or improving your professional training. On top of that, communication gets fragmented: a comment on WhatsApp, an email with a PDF, a message on Instagram. In the end, your athletes' information is everywhere and nowhere at once.
Pillar 1: Build your workout library
To manage more than 20 athletes without losing your mind, you need to standardize your building blocks. It's not about selling canned plans, it's about having a session library you can assign and tweak quickly.
- Warm-ups: Build 3 or 4 variants (mobility, running drills, activation) and use them as blocks.
- Quality sessions: Have your interval, fartlek or hill-repeat protocols pre-built.
- Logical progressions: If you know how you prepare someone for a 21k, keep that base structure ready to be "poured in" and then adjusted to each client's pace.
When you work with a platform like ATHRIX, you can save these blocks and assign them in seconds, saving you the work of typing "20' warm-up + 10x400m" for the thousandth time.
Pillar 2: Centralize feedback (save WhatsApp for what's urgent)
One of the biggest time drains for a running coach is chasing clients to find out how it went. "Did your knees hurt?", "What pace did the intervals come out at?".
If you have 25 athletes messaging you separately, your attention is scattered. You need feedback to be part of the system. The athlete finishes the run, logs their RPE (perceived effort scale) and leaves you a comment in the same place where they saw their plan. That way, when you sit down to review the week, you have the full history right in front of you, without having to scroll through endless chats.
Pillar 3: Automate delivery and billing
Selling running plans isn't just about designing the workouts. It's also about charging, letting people know when the plan expires, and handling renewals. If you do this manually, you're losing money.
A professional looking to scale needs the sales process to flow smoothly. The athlete pays, gets access to their plan, and receives their workouts. All in a single flow. This not only frees up your time, it also gives your service a much more professional image. The runner feels like they're paying for a training experience, not just a PDF that lands in their inbox.
Technology as your right hand
Going past 20, 50 or 100 athletes doesn't require working more hours, it requires working smarter. Tools like ATHRIX are built precisely so that health and fitness professionals can centralize everything: from creating personalized plans to charging for them.
By using a dedicated platform, you can see at a glance who's keeping up, who missed this week's sessions, and who needs an adjustment to their training zones — all without opening a single .xlsx file.
Conclusion
Excel was a great tool to get started, but it's the anchor holding you back from growing today. If you want your running academy or coaching service to be a real business and not a self-employment gig that eats up your weekends, you need to systematize.
Your value as a coach lies in your trained eye and how you interpret the data, not in how fast you can copy and paste cells. Start delegating repetitive tasks to technology and focus on what you do best: making your athletes run faster and better.
Want to professionalize how you deliver plans and stop losing time on admin tasks? With ATHRIX you can manage your athletes, sell your plans, and centralize all feedback in one place. Try the platform and start scaling today.
