The Marathon Route and Key Landmarks

The London Marathon 2025 route begins at Blackheath in Southeast London and finishes on The Mall near Buckingham Palace. The race passes through 32 London boroughs, taking runners past iconic locations including Tower Bridge, Canary Wharf, Big Ben, and Tower of London.

The route is divided into distinct sections, each offering unique spectating opportunities:

• Miles 0-5 (Blackheath to Greenwich): The starting area around Blackheath Park provides excellent viewing, though arrive early as this section gets crowded. The Greenwich area near the Cutty Sark (Mile 5) offers spectacular photo opportunities.
• Miles 10-15 (Deptford to Tower Bridge): Tower Bridge (Mile 13) is the most iconic point on the London Marathon 2025 route. This section draws massive crowds; position yourself by St Katharine Docks for the best views.
• Miles 15-20 (Bank to Canary Wharf): The route through the City includes views of St Paul's Cathedral. Canary Wharf offers modern skyline backdrops and typically has fewer crowds than Tower Bridge.
• Miles 20-26 (Westminster to The Mall): The final stretch passes Big Ben, the Houses of Parliament, and Trafalgar Square before finishing on The Mall. This emotional finish attracts passionate supporters.

Best Spectating Spots for London Marathon 2025

Tower Bridge remains the premier spectating location for London Marathon 2025. Arrive by 7am for good positions along the bridge approaches. St Katharine Docks offers alternative views with less crowding.

For family-friendly viewing without extreme crowds, consider positioning yourself along the Canary Wharf stretch (Miles 15-18). This modern development has spacious viewing areas, nearby cafés, and facilities. The route through Limehouse and along the Thames Path provides quieter alternatives with reasonable sightlines.

The Mall finish area creates an electric atmosphere, though access is restricted. Position yourself along Trafalgar Square or The Strand around Mile 25-26 for the emotional final stretch.

Family-Friendly Options and Activities

Taking children to watch the London Marathon 2025 requires strategic planning. Greenwich Park provides elevated viewing positions, though the gradient may challenge younger children. Bring collapsible chairs, entertainment, and snacks for the 2-3 hour wait.

St James's Park offers a relaxed atmosphere with green spaces where children can move around. Position yourselves along the route around Mile 22 for manageable crowds and reasonable views.

Several London attractions near the marathon route operate special Sunday hours. The Tower of London and Tower Bridge Experience (closed during the race) reopen early evening. Cutty Sark in Greenwich operates normal hours and provides excellent refreshment breaks during the race.

Pack a packed lunch (no glass bottles permitted) and arrive with entertainment for children. The race runs from approximately 10am finish by 4:30pm.

Seasonal Weather and What to Wear

April weather in London can be unpredictable. For London Marathon 2025, expect temperatures between 8-15°C (46-59°F). Prepare for potential rain with waterproof jackets and bring umbrellas.

Dress in layers as you'll be stationary for extended periods. Waterproof trousers, thermal layers, and windbreakers work better than heavy coats. Comfortable shoes are essential since you may stand for 3+ hours.

Bring high-factor sunscreen despite cooler temperatures—April sun reflects strongly off pavement and water.
