Where One Run starts and finishes

One Run starts at Wadi Namar, Riyadh and finishes at Wadi Namar, Riyadh. We haven't been able to place those on a map accurately enough to show one — a pin in the wrong place is worse than no pin.

These are the start and finish points, not the route. Verus doesn't hold course files for this race, and drawing a line between two pins would be a guess you might end up training on.

One Run Race Day Checklist

Tap items to mark off your race-day readiness.

0/4
  • Race number attached, and any timing chip fitted per your race pack instructions
  • Weather-appropriate kit, plus something warm and disposable to discard before the start
  • A plan for reaching Wadi Namar, Riyadh
  • A meeting point agreed with family and friends for after the race

Training Strategy for One Run

Standard Training Window

10-14 weeks is a solid window for a first half marathon; 8-10 weeks is enough if you're already maintaining a baseline mileage. Build your long run up gradually rather than jumping straight to race 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

Reduce overall mileage across the final 7-10 days while preserving short race-pace bursts. Arrive at Wadi Namar, Riyadh 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.

How many weeks do you actually need to train for a Half Marathon?

Half Marathon Nutrition & Fueling Plan

2-3 Days Prior

A normal diet is fine. There is no need to carb-load for a race of this length.

Race Morning

Eat a carbohydrate-focused breakfast two to three hours before the start, and stick to something you've already tested in training rather than trying anything new.

On-Course Fueling

Fluid at the on-course stations is usually enough; some runners take a single gel around the hour mark.

Post-Race Recovery

A mix of carbohydrate and protein in the hour or so after finishing supports recovery.

One Run Charity Places 2027

No formal charity-place scheme published — runners commonly fundraise for a charity of their own choosing.

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!
