All 260 chapters of the New Testament in three months.
Day 1 is whenever you start. There's no calendar, and no way to fall behind.
A short, deliberate sprint: Matthew to Revelation in ninety days, about three chapters a day. Reading fast is a different experience from reading slowly. At this pace you feel the shape of the whole thing — how Acts carries the gospels into the letters, how often Paul says the same handful of things, where Revelation is answering Genesis. Days are balanced by verse count rather than chapter count, so the pace stays honest.
