The 25th annual Plymouth MegaRide will take place tomorrow and thousands of bikers, pillion passengers and spectators are expected to mass on the Hoe Promenade.

As part of the Ocean City Motorcycle Festival the annual MegaRide is now one of the UK's largest charity motorcycle ride-outs with bikes, trikes, scooters and quadbikes of every shape, size, age and colour travelling from Lee Mill industrial estate out to Marley Head and back along the A38, through the city centre towards Plymouth Hoe.

Bikers are asked for a minimum £5 charity donation at the Lee Mill starting point and the total amount - barring expenses - is then given to chosen charities by organisers, The Plymouth Motorcycle Club. This year the Cornwall Air Ambulance and the Devon Air Ambulance will benefit from the bikers' donations.

Minions aplenty at a previous Plymouth MegaRide

The ride-out is led by members of the club along with a contingency of Devon and Cornwall Police motorbike cops as well as Devon Freewheelers who are volunteers who deliver much-needed blood supplies, medical samples and even breast milk.

Once on the Hoe riders, pillion passengers and spectators can browse through a range of stalls including city-based bike and clothing trade stands, food stands, safety campaigners - such as police, ambulance and fire services - as well as fair rides for children.

The Met Office say Sunday will see a "bright and breezy day" much like today [Saturday] with "pleasant sunny spells"

However, they do warn that there is the possibility of showers.

Rider and pillion prepare for the annual Plymouth MegaRide, setting off from Lee Mill industrial estate

Riders will begin turning up at the Lee Mill industrial estate from 9am and enjoy a bite to eat and hot drinks - as well as a good walk round admiring the myriad of two, three and even four-wheeled bikes parked up, before the ride-out begins at 11.30am. The route takes them up along the A38 towards the Marley Head junction, then back towards Plymouth.

Motorists coming into the city from Sunday 11.30am onwards should be patient during the event and fully prepared to share the road with thousands of bikers and passengers. In addition, road users can expect huge crowds of enthusiastic spectators along the route in lay-bys, parking spots, on bridges and on pavements.

The entertainment, including a host of bands, will begin on the Hoe at 12 noon and riders are expected to begin arriving soon afterwards. The live music begins at 2pm and ends at 4.30pm.
