Your swim, run and ride training, explained.

Simma reads every Garmin session, compares it with your own history, and answers questions about it in the assistant you already use.

Review
Simma is a game changer. It allows my clients to get instant feedback, to have all the data right there where we can connect it up, have a look and see what the results are straight away. That's going next level to what the elite athletes are dealing with.

How It Works

Garmin in.
Your assistant out.

Simma is the system of record for your training. Your assistant is where you use it — the same one you already open for everything else.

01
Garmin in
Link your Garmin once. Simma pulls your recent history and every new session as it lands — swims to the lap, runs and rides to the second.
02
Simma does the maths
Each session read against your own: pace or power at the same effort, held or faded, stroke length and rate. Then the longer view — load, fitness and form per sport, against your history rather than a generic scale. Computed once, kept as one record.
03
Your assistant does the talking
Connect Simma to Claude, or the assistant you already use, and ask in plain language. It reads the finished numbers, drafts what needs saying, and nothing is sent without you.
For Coaches

Your whole squad, inside
the assistant you already use.

Ask who needs you this week, why an athlete has gone quiet, what to change before Sunday. It answers from your squad’s real training data — the same data, the same access, as when you open the Simma web app.

Who needs me most this week?
get_coach_inboxlist_athletes
Three of your six are flagged. Marcus Reed is the one I’d start with — form −24, and his load jumped 41% off a light fortnight. Tom and Jake are worth a look but neither is urgent.
He’s racing in three weeks. Draft him something about easing off Thursday.

Saved a draft — “Thursday, and the three weeks out”. It picks up the 41% jump and his 70.3 on the 22nd, in your sign-off. Want to read it before I send?

Review
It reads what Simma already knows
Training status for every athlete, session detail down to individual sets, load history, goals, your message thread with each of them. Simma does the maths against each athlete’s own baseline; your assistant reads the result rather than re-deriving it.
It brings context Simma doesn’t have
Your calendar, your race schedule, the note you made after Tuesday’s session, the injury you know about and never logged. That is the half of coaching that never fits in a database — and it is already sitting in the assistant you use.
It drafts, and only you send
Drafts are stored in Simma, not fired off. Sending is the one irreversible step, and it takes two confirmations: your assistant has to quote the draft’s exact subject line back to Simma, and you have to approve it. The email goes out from Simma so replies thread back into the athlete’s history.
Replies come back to the same place
When an athlete answers, the reply lands in Simma against their record. Ask your assistant to read what came in and draft the responses, or schedule it to check every morning. Email is only ever the notification; the conversation lives where the training data does.
It sees exactly what you see

You sign in with your own Simma account, so the connector reaches your athletes and no one else’s. It can’t change training data, and it can’t message anyone outside your squad. Disconnect it whenever you like. Athletes get the same connector with their own tools, and never see your notes. How we handle your data.

Connect it in a minute

Add this as a custom connector in your assistant and sign in with your Simma account. That is the only value you will be asked for.

Simma is listed on the official MCP Registry as com.getsimma/simma, so assistants that browse the registry can find it without the URL. Setup guides: Claude · Antigravity.

Claude

Nothing quite like this exists for swim and triathlon squads yet — which mostly means it is unproven. The coaches using it now are the ones deciding what it becomes, so if it misses something you need, or answers the wrong question, we want to hear it. That is the roadmap. Come break it.

For Athletes

Your training,
explained to you.

You already record every session. Simma reads them all and answers the question the watch never does: what does this mean for tomorrow?

Every session, read properly
Lap-by-lap stroke and pace for swims, splits and heart-rate distribution for runs and rides, held or faded, faster or slower for the same effort. Compared with your own recent sessions, not a chart you have to decode.
Load, fitness and form, against your own history
Simma works out your training load across swim, run and ride and tells you what this week means next to your usual fortnight. No generic scale, and nothing to learn before it makes sense.
Ask your assistant, with or without a coach
Connect Simma to Claude and ask why a session felt hard, whether you are ready for the event you set as a goal, or what to do this week. If you have a coach, the same connector lets you message them. If you don’t, you get the analysis a coach would.

How’s my training going?
get_my_context
Load is up for the third week against your usual fortnight, and form sits where it does when you’re absorbing work rather than fresh. Sunday’s 3km was your longest swim in twelve weeks and you held pace across it.
Why did Tuesday feel so hard then?
find_my_sessions_by_shapeget_my_activity_detail
Tuesday was the same set as three weeks ago, done 4 seconds per 100 faster at a higher heart rate, the day after your longest swim. It felt hard because it was. Want me to tell Sarah?
