How to Invite Athletes Using Your Coaching Link

Once your coaching account exists, athletes join through a link that is unique to you. You share it, they sign up through it, and they appear in your squad. This guide covers both sides of that as the screens are today.

Where the link is

Your invite link is on your dashboard, with a copy button, and under Settings. It looks like app.getsimma.com/join/your-name. The last part is the slug you chose at signup, and you can change it in Settings at any time.

Sharing it

The link works anywhere you already talk to athletes: an email to the squad, a pinned message in the group chat, your onboarding email for a new athlete, or your website.

A short message is enough. Something like: "I'm using Simma to read your training data so our check-ins start from what you actually did. Sign up here, it takes a few minutes, and have your Garmin login handy."

What the athlete sees

1. Your name. The join page shows who they are joining, so they know they have the right link. If the slug is wrong, the page says the link does not match any coach.
2. Create an account. Name, email, password, then a verification code by email.
3. Level per sport. A short self-assessment for swim, ride and run, from "I can barely swim a length" up to "training with power and structured plans". It is a starting point, not a measurement. You can set precise thresholds for the athlete later from their settings on your side.
4. Connect Garmin. The athlete authorises Simma to receive their sessions. On Garmin's consent screen there is a Historical data option. If they turn it on, Simma loads their last sixteen weeks; if they leave it off, Simma starts from their next session and their settings card will show a note about turning it on later.
5. Their own view. Each session appears as Garmin delivers it, usually within a few minutes of the watch syncing. Messages you send them appear here as well as in their inbox.

An athlete can also connect Simma to their own assistant. They get a smaller set of tools about their own training, and if they have a coach, a way to message you. That is described on the Connect Simma to Claude page, which works for coaches and athletes alike.

What you see

New athletes appear on your squad view with a training status per sport. Until they have recorded enough sessions in a sport for a pattern to exist, that status reads Getting started. If they connected Garmin with historical data on, the last sixteen weeks arrive over the following minutes and the status settles as they land. How to Read Your Squad View explains each status.

Things that come up

Athletes without a Garmin device. Simma reads Garmin sessions. An athlete who records elsewhere will have an account with no data in it.

A Garmin account that has been linked to Simma before. Garmin delivers historical data once per Garmin account. If an athlete linked under an earlier Simma account, the sixteen-week load will not repeat on the new one. Write to us and we can help.

Stragglers. Some athletes will not click the first time. A reminder a week later is usually all it takes.

Larger squads. If you are bringing many athletes on at once, you may prefer a first wave so you can read the squad view and tune your voice settings before everyone is in. That is a preference, not a rule.

Something not right?

If an athlete hits a screen this guide does not describe, or a step fails, write to coaching@getsimma.com with what they saw. We fix the flow or the guide, whichever is wrong.
