Swimming services

The company provides private front crawl technique lessons with video analysis at Guildford Lido throughout the year. These sessions can be one-to-one (1-2-1), for two people (2-2-1) or for three (3-2-1), and at Guildford Lido a swim lane is reserved exclusively for the lesson. Lessons are also offered at local pools in north-east Hampshire and south-west Surrey.

In addition, Speedy Swimming organises adult swim groups, with technique and fitness sessions. These include:

• Fitness & Technique Squad: sessions on Fridays at 12:00, from 20 February 2026, at Guildford Lido outdoor pool. The aim is to improve stamina, speed and technique, reducing stroke count by up to 10%.
