Oysho Royal Parks Half Marathon: Course, Route Profile & Map

Course & Elevation

The race starts on South Carriage Drive in Hyde Park. The opening kilometre runs gently downhill to Hyde Park Corner, then past the Wellington Arch into Green Park and down Constitution Hill: Buckingham Palace at kilometre 1.8, The Mall at 2.4, Horse Guards Parade at 2.9.

Between kilometres 3 and 8 the course sits at river level, barely four to seven metres above the sea, and turns its tight loops there: Birdcage Walk along St James’s Park, Big Ben and the Houses of Parliament at kilometre 5.3, Trafalgar Square and the swing towards the Strand at 6 to 7, a second run down The Mall, a third pass of the palace. By kilometre 8.6 you are back at the Wellington Arch – having quietly taken back the twelve metres the start handed you.

From there the route leaves the city and stays in the parks: Serpentine Road, the loudest stretch of support on the course, a second loop over the wide carriage drives, Kensington Palace at kilometre 18.5, the Round Pond at 20, and the finish at 21.4 in Kensington Gardens between the Albert Memorial and the Royal Albert Hall. This half runs on park roads beneath old beech, chestnut and lime trees in full mid-October colour, and much of it is unbarriered – the parks stay open to the public. Over 16,000 runners are out there, most of them on a charity place, and the celebration afterwards is in the event village back in Hyde Park.

Pacing Strategy

Ninety-six metres of climbing over 21.5 kilometres sounds uniform, but only two thirds of the course is genuinely flat – the rest is spread across small ramps on the park roads, without a single graded climb. The first three kilometres drop from 16 to 4 metres, and that is where the classic trap sits: closed roads, the palace in view and a gradient that makes you ten seconds per kilometre too quick. Run the opening to goal pace, not to feel.

The race is decided between kilometres 8 and 11. Coming back up from river level to Hyde Park Corner and on into the parks costs around 20 metres of climbing, spread over three kilometres and therefore barely noticeable – if you were too fast early, this is where the pace goes first and the rhythm second.

Then come twelve kilometres of open parkland: constant small undulations, no buildings to break the wind, and long straights on the carriage drives where the pace drifts unnoticed. The four water stations sit at miles 3.5, 6.5, 9.5 and 11 (roughly km 5.6, 10.5, 15.3 and 17.7) and use compostable cups laid out on long tables – take one from further down the table rather than braking at the first. No gels are handed out on course.

Training plan for Oysho Royal Parks Half Marathon: 12-week build

As an age-group runner, expect somewhere between 80 minutes and just under three hours; the time limit is four hours and pacers run from 1:30 to 3:30. The effort is aerobic throughout and remarkably uniform: there is no climb to load the legs differently for a while, so nobody holds your pace but you. That is exactly what makes a flat half harder than its profile looks.

Preparation therefore centres on sustained speed on the flat: threshold sessions plus goal-pace blocks of five to eight kilometres inside your long runs. Because the rise at kilometres 8 to 11 and the twelve park kilometres after it decide the result, progressive long runs with the quickest section at the end are the key session. A handful of strides or short hill reps each week covers the small ramps on the park roads – no real climbing work is needed.

The conditions come with the mid-October date: mild to cool, often damp in London, and across the open ground of Hyde Park and Kensington Gardens the wind arrives unbroken. Deliberately run a few autumn sessions in wet and windy weather, test your race kit at single-digit temperatures, and factor in the long wait in the start waves – pack an old top you can throw away.

Two things are worth practising specifically. First, fuelling: the course offers water in cups and nothing else, so rehearse drinking on the move and carry your own gels. Second, running in a field – the start is in waves, much of the park section is unbarriered, and the route turns a lot of tight loops. Holding an even rhythm through the bends and running the racing line, instead of braking and surging in the crowd, saves more here than any amount of hill work.
