There is a Google map for this event.
Tewkesbury Regatta is organised by Cheltenham College.
Races normally start at about lunchtime and go on until about 6 p.m.
Have a look at the Google map for directions. Having turned off the M5, you head into Tewkesbury, then turns south on the A38, heading towards Bristol. Not very far from the town centre, take the road called Lower Lode Lane on the right. This leads directly to the rowing area. Parking is not easy but there is usually room.
It is worth taking camping chairs.
There is a good view of the whole course.
All crews get at least two races.
