Pack this

What you should know
- Bibs are typically collected in advance at the expo — same-day pickup is not guaranteed, check your start-pack email.
- The course runs Tower Bridge to Cutty Sark in Greenwich; it's a point-to-point, so plan your post-race transport back.
- Baggage trucks close well before your wave start — drop kit early and use the pen toilets before they queue up.
- Expect a rolling road closure with a broom vehicle; sweeper pace is around 16 min/mile, so know your cutoff.
- September in London is mild but showers are common — dress for 18°C running, not for standing around at the start.
