var distance = prompt("How many km did you bike on weekdays?", 5);

for (var i = 3; i < 65; i += 2) {
    var w = Math.floor((i-3)/2);
    if (w % 7 == 4 || w % 7 == 5 || i == 21 || i == 43)  continue;
    $("input")[i].checked = true;
    $("input")[i+1].style = "visibility: visible";
    $("input")[i+1].value = distance;
}

Works on Chrome, but get a few off-by-one misses... Maybe because trying to fill checkboxes for future days that can't be legally filled yet :-)

@jfcorbett: Thanks. Looks like the assumption that VCTA was based on the Old Norse calendar, in which months always start on a specific weekday across years, does not hold. And someone moved Ascension. Guess you'll have to work weekends this year.

Updated to take 2018-specific features into account. See you next year.
