1-2-1 Coaching & Swim Analysis
with Dan Bullock
Work directly with Swim for Tri Head Coach Dan Bullock at our Russell Square pool. Whether you want focused 1-2-1 technique coaching, full underwater video analysis, or cutting-edge eo SwimBETTER data metrics, choose the session that matches your swimming goals.
Dan Bullock
Dan has over 20 years of open water coaching experience and holds the highest qualification offered by the World Open Water Swimming Association. He has helped thousands of swimmers get fitter and faster, from their first novice triathlon or open-water swim through to a Channel crossing or Ironman.
Session Types
Dan offers three distinct session types depending on the depth of feedback and analysis you need. Explore each option below to find the best fit for your training.
1-2-1 Coaching
Focused, personal 45-minute coaching tailored to your current level. Includes on-surface video analysis and a follow-up drill report to accelerate your progress in the pool.
Full Analysis with Underwater Filming
Comprehensive session combining Dan's expert coaching with underwater video analysis. Review your stroke from multiple angles and understand exactly what to adjust.
eo SwimBETTER
Data-driven session using eo SwimBETTER wearable technology to measure power (Watts), 3D stroke path, and efficiency in real time with AI-optimised reports.
1-2-1 & 2-2-1 Swim Coaching
A dedicated 45-minute personal tuition session with Dan designed around your specific goals. Whether you are learning to swim, fine-tuning front crawl efficiency, building endurance, or prepping for a triathlon or marathon swim, Dan adapts every minute to your needs.
- 45-minute private 1-2-1 or 2-2-1 session in a traditional 25m pool
- Poolside technique guidance, fault correction, and tailored drills
- On-surface video capture during the session
- Detailed follow-up email with video clips and personalised homework exercises
Full Analysis with Underwater Filming
See what is truly happening beneath the surface. Many stroke flaws — such as hand pitch, dropped elbows during the catch, scissor kicks, and cross-overs — cannot be spotted accurately from the poolside alone.
Dan combines high-definition underwater filming with expert poolside review so you get visual clarity on where your propulsion is lost and how to fix it immediately.
- Submerged underwater and surface-level multi-angle filming
- Real-time visual feedback and stroke critique during the lesson
- Comprehensive follow-up report with video breakdowns and drill prescriptions
- Available as 1-2-1 or 2-2-1 sessions
eo SwimBETTER Sensor Analysis
Unlock your hidden power with objective stroke metrics. eo SwimBETTER uses wearable sensor handsets to measure power output, force distribution, and 3D stroke geometry in real time.
What is eo SwimBETTER?
eo SwimBETTER is a pair of ultra-lightweight handsets (just 30g each) worn during your swim that capture granular data on every single stroke.
Data synchronises with the cloud and connects to the eo app. Following your swim, Dan will review your metrics alongside the eoi AI analysis, highlighting where you are losing momentum and prescribing targeted corrections.
Ideal for competitive swimmers, Masters athletes, and triathletes wanting to measure swim power in Watts and integrate directly with TrainingPeaks.
Key Metrics Captured by eo SwimBETTER
Stroke Rate & Power
Measure total power output in Watts alongside propulsive force and stroke rate. Discover how power shifts as tempo increases.
Force Field
See exactly where your applied force goes — forward propulsion vs wasted vertical, downward, or lateral drag.
3D Stroke Path & Velocity
Track hand trajectory from front, side, and top-down views to pinpoint cross-overs, excessive sweep, or dropped elbows.
Consistency & Symmetry
Overlay left vs right stroke profiles to spot imbalances, stroke degradation, and fatigue patterns.
Stroke Phases Breakdown
Break down the glide, pull, and recovery phases of every stroke to maximize the percentage of time spent in active propulsion.
eoi AI Analysis & Reports
AI-optimised reports transform raw data into clear, actionable advice, reviewed and annotated by Coach Dan.
