Eastbourne Duathlon - Sunday 11th October 2020
Run 5km | Bike 19km | Run 2.5km

From the organisers of the award-winning Eastbourne Triathlon, Ironbourne Events presents the inaugural Eastbourne Duathlon on Sunday 11th October 2020. Situated in the beautiful Helen Garden at the western end of Eastbourne’s historic seafront, this event is a great opportunity for runners and cyclists to venture into the world of multisport racing. Athletes of all abilities and experience, from novice to elite, will take on the run/bike/run format. Starting from the western end of the promenade, athletes will first complete a 5km run, before heading out on a beautiful and challenging 19km cycle over the iconic Beachy Head Road. On returning to Helen Garden, athletes will then conclude with a 2.5km run before finally crossing the finish line.

Event Schedule

Registration and racking will take place from 7am at the Helen Garden. The start is a 5 minute walk from transition. The race will start at 8:30am.


All finishers will recieve a finishers medal. Trophies will be awarded for the first three male and female finishers overall and the first three male and female veterans aged 40 and over. If a veteran 40+ is amongst the first three finishers overall, the veteran awards will roll down.

Run 1

The first run of 5km will first take athletes east along the lower prom. On reaching the Western Lawns, the route will turn and climb gradually along the pavement of King Edward’s Parade before making a left turn to complete an out and back section along the gravel path. Having re-joined King Edward’s Parade, competitors will enter the Helen Garden and complete a lap of the gardens before entering the transition area.


The 19km bike is an out and back route taking athletes out over Beachy Head to East Dean before returning to climb Beachy Head once more. The route starts with the Zig-Zags climb of Upper Duke’s Drive. A flatter section then takes athletes out to Beachy Head. Having passed Beachy Head Pub, the route descends, with a couple of tight switchbacks, before a long fast section down to Birling Gap. The route then climbs slightly to East Dean where athletes will make a U-turn. On the return, the climb to Beachy Head will once again serve as our special “King of the Mountains” segment. On reaching the junction at the end of Beachy Head Road, competitors will complete a mandatory foot down stop, before making the descent back to the Helen Garden and transition 2.

Run 2

The final 2.5km run will begin heading down the pavement of King Edward’s Parade before turning left onto the gravel path. At the end of the path, the route descends to the lower prom and heads west, back towards Holywell. As a final sting in the tail, competitors will climb Holywell Drive (our run KOM segment), before finishing with a lap of the beautiful Helen Garden.
