Thames Valley tech calendar Jan – Dec 2026
Reading · Heathrow · Henley
Bray-centred 30 km radius

A year of meetups,
two conferences,
one booking trap.

Within 30 km of Bray the tech-event scene is concentrated in Reading (~20 km west). Six free meetup series carry the calendar; the only multi-day conferences are DigiMarCon UK at Heathrow T5 (3–4 Sep) and the ECMWF Annual Seminar in Reading (14–18 Sep). Anything bigger is a 36–40 km trip to central London.

The Tuesday–Wednesday trap a weekend in Bray + a meetup in Reading is structurally impossible

  • Tue 2nd Reading Geek Night runs 2nd Tue from 7pm at Zero Degrees — same night both three-stars are closed [2]
  • Wed 2nd Rust Workshop at Biscuit Factory · plus rLab's weekly open night · Windsor Castle is also shut Tue–Wed [11]
  • Conflict Fat Duck and Waterside Inn both close Mon–Tue. A Bray weekend + a meetup needs an extra weekday tacked on. parent expedition
§ 04  ·  Geography

Where the venues sit, by radius

Bray at centre · 30 km cutoff
~5 km · Thames Valley Park
Microsoft UK campus at RG6 1WG — closest tech anchor but no public events programme [20].
~14 km · Henley-on-Thames
Henley Business School Greenlands campus — Henley AI exec programmes, occasional TVAI HUB events [6][14].
~15 km · Heathrow Terminal 5
DigiMarCon UK's 2-day venue, 3–4 Sep [12].
~20 km · Reading town centre
The centre of gravity. Geek Night at Zero Degrees, Rust Workshop at Biscuit Factory, .NET TV, ISC2 TV at Thirsty Bear / CGI, rLab at Weldale Street, ECMWF Seminar at the university [1][3][5][7][10][13].
~36 km · Central London (outside)
MS Reactor Paddington, the AWS UGUK meetup, Build recaps — close but cleanly outside the 30 km radius [16][17].
§ 05  ·  Just outside the radius

Next-nearest options · 6–10 km past the line

listed for completeness only

Anything bigger than the two September conferences means a 36–40 km trip to Paddington. These are the closest London options.
