A loop, not a fixed plan
Most apps sell a plan: sixteen weeks, written once, identical for everyone at your level. Life does not cooperate. Aegis coaches the way a good human coach would, on a loop with two rhythms: every day and every week.
Onboarding is your coach's brief
A human coach starts with a long first conversation. Aegis asks the same questions, once. Everything you enter is used somewhere specific in your plan, and you can change any of it later.
What are you training for?
A race, or building fitness with no race at all. You also tell your coach about the season in your own words.
Map your season
Your races, plus the camps and holidays the plan should work around. Your A-race sets the peak.
Your sport
Your main discipline, any cross-training, and a goal such as a first 10k, a first 100 km ride or a faster half marathon.
Your numbers
Threshold pace, bike power, swim pace. If you don't know them, Aegis estimates them and plans more cautiously until it has real data.
How you rate yourself
A plain-English rating for each discipline, with room for a note. This decides what your training blocks work on first.
Your week and your life
Training days, hours, recovery days and fixed commitments. Optionally your job, family, nutrition and, for women, cycle tracking.
Your kit
Pool, bikes, smart trainer, treadmill, gym and recovery equipment. Sessions only ask for what you can actually get to.
Your routines
Short morning and evening routines, built for you or chosen yourself, to support recovery and sleep.
Then you see the plan before you start
Aegis writes a season strategy and shows you the reasoning. Once you accept it, your first four weeks are built: two in full, two in outline.
Then connect a device, if you have one
Your recent history is imported so the plan starts from what you have actually been doing. It works without a device too.

Your week with Aegis
Five steps. Your part takes a couple of minutes a day.
Check in
Sleep, energy, soreness, stress and an optional note. With a supported wearable connected it arrives pre-filled from what your body recorded overnight.
Follow the session
The workout as it stands after your check-in, sent to your watch or head unit as a structured session with every step and target in front of you.
Rate the effort
Ten tappable buttons and a note. Your finished session syncs back by itself and is analysed against what was planned.
Review the week
Too easy, just right or too hard. Flag the days you cannot train next week. See what you did against what was planned.
The plan responds
It can ease off, hold steady or offer you more, and it tells you exactly what changed and why.
You stay in control
Newer to structured training? You can make your case against a decision, once a week. Experienced athletes simply accept or decline the change.
Built around your real life
Your profile is your coach's brief
Goals, races, availability, lifestyle, health context and the kit you actually own. Sessions only ever ask for what you have access to. Save an edit and the plan reacts straight away.
Your races, camps and holidays on the plan
The season is built around your calendar. Every key race gets its own taper and a recovery block shaped to the distance you just raced.
It protects you
A rough night or heavy legs can ease today's session automatically. Mention pain or illness anywhere and it is treated as a protection signal, whatever the numbers say.
It raises the bar when you have earned it
If training has felt comfortable for a couple of weeks and your recovery is holding, the plan lifts to match you, a modest step at a time.

Built by an athlete who needed it
Aegis was started by a triathlete who couldn't swim when he entered his first race. It is designed first for beginners and for people fitting training around work and family, and the in-app handbook explains every term and every decision in plain English.
