Prepare for Great Bristol Run

A plan built from your answers and your race date.

Bristol is a port city in south-west England, built around its floating harbour and split by the River Avon. Both races follow an urban route that takes in the waterside, the main city centre roads and residential districts further out. The course is entirely on tarmac, with a number of rises that reflect the hilly character of the city.

1 km and the 10K. 40am. The race belongs to the AJ Bell Great Run series and entries are already open, which leaves plenty of time to build a full training block over several months.

The formats

When to start

A build for this distance usually runs 10 to 16 weeks. Counted back from race day, that puts the start somewhere between January 11, 2027 and February 22, 2027.

These ranges are working conventions, not a research finding — no trial has compared plan lengths against each other. What matters more is that the plan was built for the weeks you actually have, rather than shrunk down from a longer one.
