I'll admit I'm not a big comic book guy but I know enough about spidey to say Backstream fail
Long Jump: Having proportional strength to his body as a spider does, he could easily jump that far, if not he'd probably be able to pull him across the gap with his webs (We said spiderman, if Peter has the suit on he's probably wearing the shooters, or we could mean the toby mcguire one who can naturally do it)
Log Grip: His spider powers would give him the wall climbing ability to stick on and the strength to hold on even with huge drops
Hedgehog: His Spidey Sense should let him know of any pegs coming at him and he could just wall cling across the barrel anyways
Jump Hang Kai: Spider-equivalent strength should prove useful, worst case scenario web aid
Ni Ren Soritatsu Kabe: Only way he's going down is if Venom, Doctor Octopus and the Green Goblin attack him at once, He should have 3 ways to ace it, speed to do it normally, wal climbing to say f*** you human way or just web sling to the top
Tarzan Rope + Rope Ladder: With his web slinging skills he'd just use tbe Tarzan Rope and bypass the Rope Ladder
stage 2:
Cross Slider: Wall clinging and spider strength, easy pass
Swap Salmon Ladder: Dunno what specific powers he'd use but I see no problem here
Unstable Bridge: No human is failing this one, Spidey would ace it
Spider Walk: This obstacle's name says it all
Backstream: I've not known spiders to be good in water, not sure his webs would work down there either (comic book geeks correct me please) unless he shoots the supports outside which is possible I guess so for the hell of it lets keep going even though I think this is his end
Passing Wall: Spider Strength again
Stage 3:
Rumbling Dice: See Passing Wall
Iron Paddler: See Rumbling Dice (ok passing wall)
Crazy Cliffhanger: Spider Strength, Wall Climbing grip and webs, assuming he doesn't get DQ'd good
Curtain Cling: Easy for spiderman
Vertical Limit: Spider Strength and grip, if he doesn't get DQ'd for using tbe upright part and not the 1cm ledge he's good
Pipe Slider: fail due to not knowing the technique, he may get lucky and cling the platform (See Akiyama and Shunsuke and add spider super powers
), he may just grab the mat with webs, both possible so lets keep going again
Final Stage:
Spider Climb: Again, read the obstacle name
Rope Climb: *cheats and shoots webs to the top and wins*
Now if you'll excuse me I need to go rethink my life since I just made a 2500+ character post on Spider-man taking on all of 29's obstacles lol
