Mont Blanc - Single Summit Push

About

Looking at summiting Mont Blanc via the Goûter route in a single push from either Les Houches or Bionnassay. Overnight 29th July into the 30th acending through the night under the full moon. 30km+ ≈3000-4000m of elevation gain involved. Aiming to summit at around sunrise within 9-12 hours and be back down for a total of around 20 hours. Looking for another person with 4000er and glacier travel experience, optionally involved with ultra running due to the long distances and high elevation gain. MUST be pre acclimatised to altitude, with exceptional fitness and endurance Rope not necessary, I have a couple to choose from. Currently clear sky and low wind speeds forecast. However temperatures are forecast are higher than I like, may cancel or turn back as a result.
