Great South Run Race Day Checklist

Tap items to mark off your race-day readiness.

0/5
  • Race number attached, and any timing chip fitted per your race pack instructions
  • Weather-appropriate kit for an exposed seafront course — expect wind off the Solent
  • Your own gels/fuel if you have specific fuelling needs beyond what's on the course
  • A plan for reaching Southsea Common — Portsmouth & Southsea station is the nearest mainline stop
  • A meeting point agreed with family/friends near Clarence Esplanade for after the race

Training Strategy for Great South Run

Standard Training Window

6-10 weeks is a solid window for a 10-mile race. Combine a weekly long run with threshold work so you can hold pace over the full distance.

Terrain Specificity

This is a largely flat course, so most of your long runs can mirror that — flat and steady, building time on feet rather than hill strength.

The Taper Phase

Ease off mileage in the final week, keeping a couple of short, sharp race-pace efforts to stay fresh. Arrive at Southsea Common, Portsmouth fresh, energized, and primed — not fit, fresh.

Pacing Execution

Lock in your target pace using the interactive splits calculator below — no official pacers are confirmed for this event, so a pace band on your watch is the more reliable option.

Fuel & Hydration Prep

Test your race-day fuel and hydration plan on your long training runs, not for the first time on race day — check the Race Day Checklist below for what's actually on this course.

10-Mile Nutrition & Fueling Plan

2-3 Days Prior

A 10-mile race doesn't demand the same carb-loading as a half or full marathon — a normal balanced diet with a slightly larger carb portion the night before is enough for most runners.

Race Morning

Eat something light and familiar 1-2 hours before the start — this is a shorter race, so a heavy breakfast can do more harm than good.

On-Course Fueling

On-course drink station contents for this event weren't published at the time of writing — most runners won't need fuel for a 10-mile race, but carry water if you prefer to.

Post-Race Recovery

A mix of carbohydrate and protein in the hour or so after finishing supports recovery — Southsea has plenty of seafront cafes and restaurants nearby.

Great South Run Charity Places 2026

Charity places are available through numerous partner charities, including Alzheimer's Society (the official charity of the AJ Bell Great Run Series), GOSH Charity and Macmillan Cancer Support. Fees and minimum fundraising targets vary by charity.

Impactful Storytelling

Lead with your personal story — explain why the charity matters to you. Personal connection generates 3x more support than a generic link broadcast.

Social Campaign Milestones

Share key training milestones on Instagram (first 10-miler, peak week, race week) with your fundraising link in bio. Publicly thanking donors prompts secondary gifts!

A smaller area with fewer large hotels than central Portsmouth.

Portsmouth city centre / Gunwharf Quays

Pros

More hotel choice, with good transport links to Southsea and easy access to Portsmouth Harbour station.

Spectator & Cheer Guide

Cheer Zones & Hotspots

The Southsea Common start/finish area and the seafront along Clarence Esplanade and Eastney Esplanade are the easiest places to watch from.

Course Navigation

Because the course runs out-and-back along the seafront, spectators based near Southsea Common can often see runners pass more than once without moving far.
