A final stage and abbreviated to Paris only but this wont alter the sport. A prestigious stage win awaits and potentially a duel between Tadej Pogaar and Mathieu van der Poel.Stage 20 Review: if a grand tour is an exercise in hierarchy to quote Antoine Blondin, or a Bayesian simulator to use science, then how much can the last mountain stage tell us? Even a day with 5,450m of vertical gain and 70 points for anyone capable of passing the marked mountain points first was probably going to confirm rather than reveal.Still, Theres plenty to be said for replicating results on a day when many struggled to hoist themselves out of bed and even scaling a bridge over an autoroute was sapping. Richard Carapaz proved he could even improve on the performances of recent days made him the rider of the day, going from a one point lead in the mountains competition to a 56 point unassailable and incontestable win in the mountains competition.Similarly Mads Pedersen hauled himself over the Alps, attacking at one point to bridge across to the breakaway and then take maximum points at the intermediate sprint to secure the green jersey, an immense ride. The Tour has its Supercombatif prize and its surely between Carapaz and Pedersen, probably Carapaz but there are good arguments to litigate either way.The days breakaway was reduced to Carapaz, Sep Kuss and Jai Hindley on the lower slopes of the Col de la Sarenne. Another day, another trio starting the climb to Alpe dHuez with three and half minutes lead. But this time Pogaar wasnt in pursuit mode.The higher slopes of the Sarenne had no crowds, the road closed to spectators. It was pleasant to see the mountain like this, and no bad advert too for cyclists wanting to explore this road. But also a premonition of what awaits us after the Tour when the sport reverts to sparse crowds and silence.Kuss led over the Sarenne, but only just. Carapaz had the American in sight and was closing. Then Kuss crashed twice and the second time he was lucky there was netting on the exit of the bend, while Carapaz sped past. Despite the dirt on his kit from falling Kuss looked the fresher climber and could have reversed matters. Only Carapaz is among the cast of riders who can be impossible to bring back if they get five metres.Behind Decathlon-CMA CGM had tried to ratchet up the pace in an all-or-nothing move to dislodge Isaac del Toro off third place overall only it came to nothing with Seixas unable to sustain the move and cracking, while Del Toro had the luxury help of Tadej Pogaar. Pogaar could have won the stage if he wished but played butler, a high altitude Jeeves.Evenepoel attacked on the final run to Alpe dHuez, symbolic perhaps but notable as hed survived 5,000m of vertical gain, each stomp on the pedals in the final kilometres a serving to every media outlet in Belgium whod declared he was not a grand tour contender.As Pogaar and Del Toro came into the finish together they were photo-bombed by Lenny Martinez who secured his fifth place overall, albeit 13 minutes down but hell take plenty from the consistent performance and how he was one of the few to hold firm in the third week, all while having turned 23 during this years Tour.The Route: On nest pas a Thoiry, ici. Well almost, theres a presentation in Thoiry for the crowds and host politicians but then the riders are bussed to Paris. Its 89km and laps of the 15km long Champs-Elyses Montmartre circuit, reduced from 133km because of a police shortage with the emergency services mobilised to help with public safety, notably in the Cap Ferret/Arcachon area. In pure cycling terms nobody is missing out on the early parade and we might see a lap or two reserved for this before the racing begins.If theChamps-Elyses-Montmartre circuit already feels familiar theres still a difference as after the descent of Montmatre, the course takes the riders to the Place de lEtoile/Arc de Triomphe and then to the Champs-Elyses. Last year the descent led to the Place de la Concorde. The meaning here is that theres 10km to the finish from the top of Montmartre when there was 6km last year so more chance for teams to organise a chase.The Contenders: the circuit has a feel of a spring classic with the repeat cobbled climbs and if its only 89km everyone is tired and so it doesnt need 200km to make the difference.Mathieu van der Poel (Alpecin-PremierTech) is the obvious pick, the punch to jump away on the climb, the ability to win the sprint and hes had this stage in mind for a long time. Jasper Philipsen is a second card to play in the sprint.Tadej Pogaar (UAE) got beaten here last year, one of the rare moments he lost a bike race in a straight contest. Hes been talking about this stage too and this makes life harder for the sprinters as his moves will distance them. Hell get extra stimulation from going up against Van der Poel, his arch rival for the classics.Mads Pedersen (Lidl-Trek) ought to be tired but so far hes been a force of nature in this Tour.Olav Kooij (Decathlon-CMA CGM) and Biniam Girmay (NSN) can hope for a sprint and an opportunity.Jayco pair Michael Matthews and Mauro Schmid have a chance. Netcompany-Ineos still have chance of salvation and Filippo Ganna might be their best bet. Theres no French stage winner so far and Romain Grgoire (Groupama-FDJ) has a chance but hes looked fried.Van der PoelPogaar, PhilipsenKooij, Matthews, Girmay, Schmid, KanterWeather: sunny and 24C.TV: KM0 is at 5.55pm and the finish is forecast for 7.30pm CEST.The post Tour de France Stage 21 Preview first appeared on The Inner Ring.
