WORTH NOTING ON TV

* SATURDAY

Tour de France (ABC, 4:30-6 p.m.): Same-day coverage from Liege, Belgium, of the 82nd running (pedaling?) of the great bicycle race - a 20-stage, 2,257-mile event that is the most grueling of its kind in the world.

(Coverage continues the following two Saturdays and on Sunday, July 23).

* SUNDAY

Wimbledon (NBC, 9 a.m-3 p.m., EDT): The tennis world's most prestigious event concludes with the men's final from London's All England Tennis and Racquet Club. This marks the 17th year the men's event has been covered live.

Charlemagne (The History Channel, 9-11 p.m.): Over three consecutive nights, this channel is offering a dramatized biography of one of the few figures widely known from an otherwise obscure period - the late Middle Ages.

The international production, originally aired in Europe, is directed by Britain's distinguished Clive Donner and uses English, French, and German talent. Originally the actors spoke in several languages, but the production was later dubbed in English.

The plot traces Charlemagne's epic story as he conquers most of Europe and eventually defends Rome and Pope Leo III against the Byzantines. The big moment comes when he is crowned ''Emperor Charlemagne I'' of the Holy Roman Empire - a group of states that, as history teachers delight in pointing out, was neither holy, nor Roman, nor an empire.

* TUESDAY

All Star game (ABC, 8 p.m. to conclusion, EDT): Major League baseball is fielding the 66th edition of its annual summertime classic pitting the National League against the American League.

Players for each side's starting lineup - except for the pitchers - were chosen by a vote of fans.

The game will be played at The Ballpark in Arlington, Texas.
