Meet at 10:30 at my house in Marple (or join us anywhere along the route), then a leisurely, scenic cycle ride through Glossop to Hadfield and a stop for refreshments at around 10:45 at Dolly's Café in Hadfield. Leave the café at 12:30, then a leisurely, traffic-free cycle along to the end of the Longdendale Trail to the Woodhead Pass to watch the Tour de France cyclists shoot past. Aiming to arrive there at about 1:30, just before the caravan passes. The first cyclists should arrive between 3:13-3:30.
Then a leisurely cycle back for a couple of well-deserved beers.
Note that the trail has some gravel sections, so to avoid punctures, a bike with knobbly tyres is strongly recommended.
