Tessa

Battersea Park 10K · 26 September 2026

49:58

Tessa came to coaching after a 10K PB attempt that had not gone to plan. In her account of the next ten weeks, she describes a structured plan, support after each run and adjustments when life got in the way. At the end of the block, she ran 49:58 on chip time at Battersea Park, reaching her sub-50 goal.

Tessa supplied a chip-time result screenshot on 13 October 2026 showing 49:58. Her earlier 49:30 watch time and Strava’s 49:31 estimate are separate measurements. Training duration comes from her testimonial.

“Sam was always encouraging and supporting whilst also providing such insightful information following each run that helped me understand the method behind the plan”

Scored off his own Garmin file each week, against the session he was actually given. The two scores in the eighties at the end of August are race week, where the job was to run slower than he wanted to.

In their words

Having Sam as a coach is on a completely different level to any app. My training is tailored using my data, sleep, heart rate, cadence, constantly adjusted based on how I am actually feeling and performing. It is more than a plan. It is detailed, proper coaching.

Callum B.

First coach who actually reads my Garmin data before writing the plan. Most just send a generic template and hope. Sam adjusts every week based on what my body did, not what the spreadsheet said it should. Malaga 2026 feels different.
