Coach first.

He coaches swimmers at ANO Glyfadas and triathletes across Greece, from the first open-water start to the full distance.

Swim technique before volume

Most triathletes lose time in the water. The stroke gets fixed first, then the distance is built on top of it.

Plans built around your week

Work, family and sleep are part of the plan, not obstacles to it.

Coached by someone who races

Every session he prescribes is one he has done himself, on Greek roads and European start lines.

ANO Glyfadas

On the pool deck at ANO Glyfadas, Alex coaches swimmers every week. The same technique work sits under every triathlete he trains.

Alex Endurance Gang

Red and yellow shirts on start lines across Greece, from Chania to Almyros. The group he trains with, and the group he built.

Start Training

Tell Alex where you are now and where you want to finish.

Triathlon coaching

Sprint to full distance. A structured plan, weekly review and a race-day strategy for every event.

Swim technique

One-to-one and small-group sessions on stroke, breathing and open-water skills.

Run & endurance

Road and marathon blocks for runners who want to finish strong, not just finish.

Alex Endurance Gang

Train with the group. Shared sessions, shared start lines, the same red shirt.

Coaching interest
A race, a distance or a time. For example, your first 70.3.
