TRAIN FOR THE COURSE

Great Bristol Run training guide

The Great Bristol Run half marathon starts on Colston Avenue, twists through the city centre past Queen Square and Castle Park, follows the harbourside and runs out and back along the Portway before finishing on Anchor Road. The organiser calls it relatively flat, so it suits steady, even half-marathon running.

01 / KNOW THE ROUTE

What the course asks of you

Twists and turns in the city centre

The organiser says the first three and a half miles twist and turn around Queen Square and Castle Park. With lots of corners and a big field, this is not the place to chase pace. Run the tangents sensibly and let the crowd thin out.

Harbourside and Cumberland Road

The route crosses the river on Prince Street Bridge and follows a waterside stretch along Cumberland Road. The 10K and half share the course for over five miles. Use this section to settle into the effort you plan to hold.

The Portway out-and-back

Half-marathon runners then split off onto the Portway for what the organiser calls a fairly straightforward out-and-back. You turn just after nine miles, rejoin the 10K route at Merchants Road and head for the finish on Anchor Road. Straight out-and-back roads are a good test of rhythm and concentration.

02 / BUILD THE BLOCK

How to prepare

Build steady half-marathon endurance

Grow your weekly long run gradually so that 13.1 miles feels comfortable before race day. Add steady or tempo work a little slower than 10K effort and extend it through the block.

Practise rhythm on straight roads

For the Portway section, include out-and-back runs on long, straight roads or paths. Practise a smooth turnaround and returning to your rhythm straight away. The organiser suggests traffic-free riverside routes around Bristol for this.

Keep some hill work

Although the route is known for being flat, the organiser still recommends hill training for strength and stamina. A weekly set of short hill reps or a hilly easy run is enough to prepare for the gentle undulations.

Keep the running and strength work in one place. Explore MaxMile for your Great Bristol Run preparation, or compare the levels of personal coaching.

03 / PUT IT INTO PRACTICE

Pace the race you have trained for

Start in your allocated wave; you can move to a slower wave but not a faster one. Treat the twisty first three and a half miles as a controlled opening and avoid surging around other runners on the corners.

Find your rhythm along the harbourside and onto the Portway. The turn just after nine miles is a useful check: if you feel controlled, gradually increase the effort from Merchants Road to the finish on Anchor Road.

04 / MAKE ROOM FOR TRAINING

When should your block start?

The 2027 Great Bristol Run is on Sunday 9 May. A 12-week half-marathon block would begin around Sunday 14 February 2027, or a 16-week block around Sunday 17 January. Easter Sunday (28 March 2027) falls in the middle of the block, so plan your key long runs around the holiday weekend.

Most of your longest runs and steady sessions will fall in March and April. The early May bank holiday is Monday 3 May, six days before the race, which is already taper time. Keep that week light and save the travel and late nights until after race day.

05 / SORT THE PRACTICAL BITS

Kit and race-weekend planning

Your race number, with its timing chip, should arrive about four weeks before the run. Late entries and overseas runners collect theirs from the information point on the Saturday before or the morning of the event. Fill in the baggage label on your number before you leave home. Baggage buses are close to the start.

In 2026, half-marathon waves started at 08:30 and the 10K followed later in the morning. Check the 2027 event guide, sent with the ‘One Month To Go’ email, for your wave time and start map.
